Chinese Foreign Minister Wang Yi on Monday declared Chinas commitment to upholding multilateralism and multilateral trade rules.The United States pursues unilateralism and prioritizes its own nation, placing its own interests above global public interests, said Wang, also a member of the Political Bureau of the Communist Party of China Central Committee, throughout the BRICS Foreign Ministers Meeting in Rio de Janeiro.Wang regards it as necessary to promote multilateral trade rules.Having long gained enormous benefits from open market, the United States is now using tariffs as leverage to extort expensive demands from other countries, he said.If one chooses to stay silent and compromise, it will just push the bullies to push even more, Wang warned.He prompted BRICS nations to collectively oppose all types of protectionism and securely support the rules-based multilateral trading system with the World Trade Organization at its core.
