BEIJING, July 5 (Xinhua) -- The United States' trade bullying by pressuring trading partners with tariff threats goes against the times, China's Ministry of Commerce (MOC) said Thursday.

The United States has threatened to impose tariffs on all of China's exports to the country worth 500 billion U.S. dollars and has sent similar threats to other trading partners, MOC spokesperson Gao Feng said at a press conference.

"China will not bow to threats or blackmailing, and our resolve to safeguard global free trade and the multilateral mechanism will not waver," Gao said.

China will work with other countries to fight against the regressive tide of backward, outdated and inefficient protectionism and unilateralism, and will maintain a stable and predictable global economic and trade environment, Gao added.
