Why is China suing the US at the WTO?

US President Donald Trump on Saturday issued instructions to implement a 10 percent tariff on products imported by the US from China, and 25 percent on Canadian and Mexican products.

China's Ministry of Commerce said Beijing will retaliate against America's wrong move of raising tariffs by filing a complaint with the World Trade Organization (WTO), and will take similar measures to firmly safeguard its rights and interests.

in response to a reporter's question about the country's response to the US announcement that it would impose 10 percent tariffs on Chinese products, the Chinese Ministry of Commerce added: "In response to the United States' wrong actions, China will complain to the World Trade Organization (WTO) and take relevant countermeasures to protect its rights and interests."

China's Ministry of Commerce also pointed out that the unilateral imposition of tariffs by the United States seriously violates the rules of the World Trade Organization, which is not only not conducive to solving its own problems, but also undermines normal economic and trade cooperation between China and the United States .

The Chinese Foreign Ministry also announced Beijing's dissatisfaction with the US announcement of a 10 percent tariff on Chinese products, and stated that Beijing firmly opposes this and will resolutely safeguard its legitimate interests by taking countermeasures 

China's Foreign Ministry said there are no winners in the trade and tariff war, noting that the unilateral imposition of tariffs by the United States seriously violates World Trade Organization rules, which not only fails to solve its own problems, but also harms both sides and the world.

Research by the Tax Foundation shows that Trump's proposed tariffs would impose an additional $830 in taxes on each American household this year alone. Economists also worry that the Trump administration's tariffs will have a negative impact on American households and the country's economy.
