China on Monday launched a case against the United States with the World Trade Organization over import duties, CNBC reported.

The Chinese commerce ministry said the latest set of sanctions violated the consensus reached by leaders of China and the U.S. in a meeting in Osaka, Japan, in a statement obtained by the outlet.

The latest tariffs, which went into effect Sunday, affect $112 billion of goods, including Chinese footwear, smartwatches and flat-panel televisions.

Those came in response to China setting new tariffs including on crude oil.

Trade tensions between the U.S. and China have escalated in recent weeks as negotiations have stalled.

The U.S. has scheduled another round of 15 percent tariffs for Dec. 15 covering about $160 billion in Chinese imports. Beijing has vowed retaliatory tariffs that, combined with the Sunday increases, would reportedly cover $75 billion in American products should the Dec. 15 tariffs take effect.

Chinese state media on Sunday knocked the U.S. for the continuing tariffs, arguing they would hurt American interests as well, according to Reuters.

“The United States should learn how to behave like a responsible global power and stop acting as a ‘school bully,’” the official Xinhua news agency said, Reuters noted.

“As the world’s only superpower, it needs to shoulder its due responsibility, and join other countries in making this world a better and more prosperous place. Only then can America become great again,” Xinhua added.
