China urged the European Union to value the overall state of mutual trust and cooperation between them, said the Ministry of Commerce.
Shu Jueting, the ministry's spokeswoman, made the remarks on Thursday in response to media reports that the European Union has proposed sanctions on seven Chinese companies that are accused of selling microelectronics and other products to Russia.
Shu said that China and Russia have engaged in normal economic and trade cooperation on the basis of mutual respect, mutual benefit and win-win outcomes.
The Chinese authorities have repeatedly clarified China's position on the Ukraine issue, stating that China will not add fuel to the fire or take advantage of the situation for its own benefit, Sht said.
"We firmly oppose the imposition of unilateral sanctions and long-arm jurisdiction against China, which are not authorized by the UN Security Council and have no basis in international law, on the grounds of China-Russia cooperation," she said.
China hopes that the EU will cherish China-EU mutual trust and cooperation, act prudently and not set a bad precedent, she said.
