BEIJING - China's position on tariffs is very clear, and there are no winners in tariff wars, the Chinese Foreign Ministry said on Tuesday.

Spokesperson for the ministry Mao Ning also said China will firmly safeguard its legitimate rights and interests.

Mao made the remarks at a regular news briefing after US President Donald Trump said Monday that any country doing business with Iran will pay a tariff rate of 25 percent on any business conducted with the United States.
