BEIJING (Kyodo) -- China will raise the rate of retaliatory tariffs on all U.S. goods to 125 percent on Saturday, up from the 84 percent it imposed earlier this week, the Finance Ministry said Friday.

The announcement comes after U.S. President Donald Trump raised total U.S. duties on all Chinese items to 145 percent, further escalating the trade war between the world's two largest economies.

Beijing also said it has filed another lawsuit with the World Trade Organization over the latest U.S. tariff hikes.

Trump said Wednesday he will pause for 90 days the implementation of steep tariffs on goods from dozens of trading partners, with the exception of China, imposing an additional 125 percent duty on all Chinese imports on top of the 20 percent already in place.

China's Commerce Ministry said the U.S. imposition of unilateral tariffs "seriously violates international economic and trade rules" and "causes major shocks and severe turbulence to the world economy, global markets, and the multilateral trading system."

"The excessively high tariffs imposed by the U.S. on China have become a numbers game and have no practical economic significance," the ministry said.

"If the U.S insists on continuing to infringe on China's rights and interests, China will resolutely take countermeasures and fight to the end," the ministry added.
