KYIV/BEIJING (Reuters) -China demanded on Thursday that Ukraine immediately remove more than a dozen Chinese companies from a list of firms designated as "international sponsors of war", saying it wanted Kyiv to "eliminate negative impacts". The remarks came after Reuters reported that China's ambassador in Kyiv had told senior Ukrainian government officials last month that the inclusion of the companies on the list could hurt bilateral ties. "China firmly opposes the inclusion of Chinese enterprises in the relevant list and demands that Ukraine immediately correct its mistakes and eliminate negative impacts," a Chinese foreign ministry spokesperson told Reuters after the report was published.
