When asked to comment on US President Donald Trump's announcement on Wednesday that a 50 percent tariff would be imposed on imported copper on the grounds of national security, Foreign Ministry spokesperson Mao Ning said on Thursday that China's position on this issue is very clear.

"We have always opposed overstretching the concept of national security. We also always believe that there is no winner in tariff wars or trade wars, and the abuse of tariffs is not in the interest of any party," said Mao.
