The Ministry of Commerce said China has always opposed unilateral tariff hikes and urged Mexico to correct its wrong practices of unilateralism and protectionism.

The remarks were made in response to a media query regarding the Mexican Congress's approval of a proposal to raise tariffs by up to 50 percent next year on imports from China and a number of other countries.

A ministry spokesperson said in Beijing that the measures would substantially harm the interests of Mexico's trading partners, according to Xinhua News Agency.

The spokesperson added that Beijing welcomes relevant countries to resolve economic and trade disputes through trade agreements, but no such agreement should be concluded at the expense of global trade development, nor should it undermine China's legitimate interests, Xinhua reported.

"We hope that the Mexican side will attach great importance to this matter and act prudently," said the spokesperson.
