Well, theres no doubt what was the Biggest International event of this week, its been trailed for months, but now donald trump has finally been sworn in as the 45th president of the United States. One nation who will be watching the New American Leader closely is china. Mr trump broke with decades of precedent last month by taking a Telephone Call from a Telephone Call the taiwanese presiden, a move that has angered beijing which regards taiwan as part of china. State media said china would take off the gloves if such provocations continue. AsJohn Sudworth reports, in china, mr trump has gone from a figure of fun to someone whos provoking a lot of anger. Not everyone in china is taking donald trump too seriously. His inauguration this week comes just ahead of the Chinese New Year of the rooster. And this factory is making, well, giant trump lookalike chicken balloons. The orders are flowing in, we can barely cope, the boss tells me. But increasingly, mr trump is becoming a target of anger, rather than a figure of fun. Mock ups of taiwanese ships provide shooting practice at this Chinese Military museum, just across the taiwan strait. While us president s have long avoided challenging beijings claim to sovereignty, the so called one china policy, mr trump says he might. Chinas military, especially our navy, is growing stronger. We dont fear us provocation, this man tells me. We want peace, but if they cross our red line we have to take measures, this woman agrees. Last week, in a move seen by some as intended to make that very point, china sent its Aircraft Carrier through the taiwan strait. And Chinas Communist Party run newspapers have issued a stark warning, telling mr trump that if he changes us policy, beijing will have no choice but to take off the gloves, and that china will mercilessly combat those who advocate taiwans independence. These Chinese Workers make luxury marble products for the us market. For them, the biggest fear is not rising military tension, but a trade war. Their American Boss believes mr trumps threatened tariffs will do nothing to change the basic market reality. Hiring one worker in the states, i could hire five to six in china. So moving our business to the states would impinge into our margins which would then reflect on consumer pricing, and it would be very difficult to run a business that way. The worlds about to find out whether one of the most vital and complex bilateral relationships is to undergo a profound change. Before his election, china could simply dismiss Donald Trumps rhetoric as the Overinflated Blhuster of the campaign trail, not any more. And china is making it increasingly clear that while it has a lot to lose, so, too, does america and the wider world. John sudworth, bbc news, beijing. To syria now, where the United Nations says 40,000 people have returned to their homes in the east of aleppo, the city devastated by years of civil war. Most are living on aid, in very difficult conditions. Syrias largest city became a major battleground in the summer of 2012, but after four years of bloody conflict, Government Forces cut off the rebels supply lines and they were able to take full control at the end of last year. Jeremy bowen has been back to Eastern Aleppo and found a city still haunted by the conflict. This is the calm after the storm. The final battle for aleppo swept through the city like a man made malevolent tornado. All sides in this war were prepared to destroy aleppo to possess it. In the end, the firepower of the regime and its russian and iranian allies was too much for the fractious Rebel Coalition that controlled east aleppo. This city is the key to northern syria. Right across the country, rebels who are still fighting, are on the defensive. Explosions the battle for aleppo lasted four years. More than 200,000 civilians were trapped in the heat of the fight. Attacks on civilians by any side in the war are crimes if it can be proved they were deliberate. Zakaria Mohammed Juma lost his leg in east aleppo three months ago. At a clinic run by the International Committee of the red cross, hes being measured for a prosthesis. Rehabilitation is painful. When you cant walk, supporting a family is even harder. It will take years and billions to rebuild. The east side of aleppo and much of the old city is in ruins. With a photo of his clothes shop, salah stood in front of where it used to be. Ive seen this much damage elsewhere in syria, but never in such a wide area. Abu mahmoud is one of the first to return to his neighbourhood. If only theyd take away the rubble, he said, all the neighbours would come back. This corpse was still lying on the road a month after the battle, more are certain to be buried in collapsed buildings. Abu mohammed, collecting firewood, showed where a Mortar Fragment had hit him. Look, he said, they took out my spleen, a kidney and part of my intestines. Ive had many operations. In every queue for emergency aid, there are tragedies. This child, who is 12, has seen more than anyone should in a lifetime. Her grandmother is using all the strength she has left to care for her surviving grandchildren. Translation my daughters 15 Year Old Girl and her son, who was seven, were killed. My sons three year old daughter lost a leg. Another grandson, aged seven, lost a hand. My familys houses were all destroyed. Translation we dont know whats hidden in our future. The war has damaged all of us. My cousin lost her leg. I saw with my own eyes my other cousin, his intestines were out of his body. President assads resurgence in aleppo means talk about forcing him out sounds more hollow than ever. He is the strongest hes been since the war started. The empty, ruined, Silent Streets on the former front lines feel oppressive. No one has tried to move back here, its haunted by violence and death. That is a home made mortar, designed and built by the rebels and in itself, its a fearsome weapon. But it is nothing compared to the power of the Russian Air Force and the military know how of the iranians and their lebanese allies. Foreign intervention has transformed this war and the way its looking right now, foreigners, not syrians, will dictate the way the war ends. The sun sets in aleppo on a dark, cold and broken place. It feels like a post war city, but this is not a post war country. Syria has a fragile partial truce. For the first time, the president and his allies can smell victory, but they are not there yet. Jeremy bowen, bbc news, aleppo. There were fears of a return to the tribal politics of the past in Northern Ireland after its Power Sharing Executive collapsed, triggering new elections to the assembly in march. Its all over a Controversial Energy scheme which could cost the taxpayer £500,000,000, but its caused a deep riff between the two Main Partners in the executive, sinn fein and the unionist dup. Gavin hewitt reports from stormont on what it means for the Northern Ireland peace process. The 10 years, power has been shared in Northern Ireland. It was one of the Foundation Stones of peace. Today, that Power Sharing Government collapsed. I propose that a draft Order In Council be brought forward shortly to set an election date of thursday, 2nd march. No one should underestimate the challenge faced to the Political Institutions here in Northern Ireland and what is at stake. The trigger for the breakdown was a row over a controversial green Energy Scheme drawn up by unionist minister, Arlene Foster. But the bitter arguments over the scheme exposed growing tensions between nationalist and unionist politicians. I think its both parties, personally, and ifind it very disappointing and very, very sad. Its the tribal politics, you know, i feel like were back in the 80s and i was really hopeful that for the future generations that they would have a different story. Theres no appetite for a return to any sort of violence at any stage or form in the near future. I think that possibly what will happen is well be led through another couple of years of political insecurity. At stormont, the Northern Ireland assembly depends on unionists and nationalists sharing power. Today, both main parties were asked to submit a name for one of the two top posts. First up, the democratic unionist party. Mr speaker, i very readily. And they backed their current leader. Nominate Arlene Foster to be the first minister. Thank you. Next up, sinn fein. There can be no return to the status quo. If something is broke, you stop and you fix it. That is the sinn fein approach. But they refused to put forward a name, so ending the Power Sharing Government. What does all this mean uncertainty for Northern Ireland. Without an executive, key areas of government will be stalled and then, most importantly, theres brexit. Where will be the Northern Ireland voice when crucial decisions are taken . We are in a very grave situation going into this election and the timing of it, when Northern Ireland has no budget agreed, when we are facing into brexit and when were also coming to the end of the Financial Year is possibly the worst time that we could be entering into this kind of disarray. Recent years have changed Northern Ireland, but the shadows of the past still make compromise difficult. Gavin hewitt, bbc news, belfast. Some still say theyre confused, but we did get some clarity this week on britains plans for brexit as theresa may announced her i2 point plan, including a pledge to leave the Single Market. The Prime Minister insisted that people were coming together, but she also acknowledged just how divisive last years Referendum Campaign had been. We sentjeremy cook to see how those on different sides of the argument felt about her speech. Boston, an ancient english town, a changing landscape. On the bus, plenty of support for the Prime Ministers speech, the brexit vote here was 75 . More than one in ten people here are eu migrants. We want that cutting, definitely. What effect has it had on the town . This town . Yes. Its killed it. Is it a price worth paying to come out of the Single Market in order to control immigration . I think so, yes. Youve got to control it in some way. At the boston body hub, its 60s dance work out. The project is largely eu funded, but most here voted brexit. Many worried about levels of immigration and the impact on their town. Its got too much now. So. The worry is we might lose some trade with europe because of controlling the borders. What do you think about that trade off . The trade off, i think, will be worth it because i think britains big enough to take care of itself. I think britain could cope. Youre confident, arent you . Im confident britain can cope. Its Great Britain it always has been, it always will be. I think europe need us. Outside boston, the agricultural heartland. Many crops being prepared today will need Migrant Workers to pick and to process. Within the industry we need labour and without it we will starve. What would you say to theresa may then in terms of what you need now as an industry . I am hoping from this that shes going to allow skills and labour to be filled in the farming community, within packers, within processing, within the field labour, wheres its required. These workers are essential to you, arent they . They are absolutely essential. An hours drive and were on the banks of the trent. In rushcliffe, they voted 57 to remain in the eu. At the spoke and coke cafe and bike shop, a different view of todays speech. I voted remain, and i was quite surprised by the outcome of the vote, but theresa may has outlined today is what the country voted for, which is brexit. And i think we need clear leadership to make sure that thats what happens. Not everyone here is quite as relaxed. I dont think we realise how bad it is yet. Do you think were any clearer tonight, after theresa mays speech, about what brexit means . No. No, i dont. Essentially, her message was the same brexit means brexit. But we still dont really know what it means for the Prime Minister then, brexit remains the greatest of political challenges, in this still divided nation. Jeremy cook, bbc news, nottingham. The Lancaster Bomber became one of the most famous and effective aircraft to take part in world war ii. It played a crucial role in securing victory for the allies, but only two of them are still able to fly. One family is hoping that will change thanks to a remarkable 30 year Restoration Project which they hope will see another Lancaster Return to the sky. Tim moffatt reports. Archive skipper, front doors open. Wartime recordings of a lancaster aircrew. Archive steady. Britains most famous bomber. Archive bombs going in a minute. Although this one hasnt flown for a0 years. Its the sight and sound, when you hear those engines revving, you know, therejust isnt another sound like it. There just isnt. Just over 7,300 lancasters were built. News reel special missions included the dambusters raid. Almost half were lost in combat during world war ii. But for Harold Panton and his family, the desire to fully restore one is personal. It brings many memories back, i think. Thats what it is. His brother, christopher, a member of Bomber Command, died on a mission over germany in 1944. Harold and his other brother, fred, wanted to restore an aircraft to honour those who never came back. In 1983, their search finally ended. We knew that its either now or never because wed never get another chance to buy a lancaster. Fred died four years ago, before the family dream of seeing this lancaster back in the sky could be fulfilled. Freds grandson, andrew, is determined to make it happen. Lancaster parts are very hard to come by, so you snap up parts when they become available. There are a few companies that did buy up old stock after the war, but then people brought random parts and have had it their house or garage for 30, a0 years. Its such a tight squeeze, isnt it . Yeah, its very tight inside, added to by the fact that theres a lot of equipment and the main spars come through as well. So this is like the main backbone of the aircraft . These spars are, as you said, the backbone, its where the main strength is. So its very important for our re
