Russian Foreign Minister Sergei Lavrov visited Congo Republic on Monday, the second leg of an African tour aimed at strengthening Moscow's ties with a continent that has refused to join Western condemnation and sanctions over the Russian invasion of Ukraine. African countries, which have a tangled legacy of relations with the West and the former Soviet Union, have largely avoided taking sides over the war in Ukraine. Many import Russian grain and increasingly energy too, but they also buy Ukrainian grain and benefit from Western aid flows and trade ties.
