“Did China ask us if it was OK to devalue their currency (making it hard for our companies to compete), heavily tax our products going into…their country (the U.S. doesn't tax them) or to build a massive military complex in the middle of the South China Sea? I don't think so!” Trump wrote in two separate tweets on Sunday evening.

The tweets come several days after Trump’s conversation with Taiwan’s president, which broke years of United States diplomatic protocol and risked a rift with China.

China said on Saturday that it raised a complaint over the call.

"We have noticed relevant reports and lodged solemn representation with the relevant side in the United States," the country’s foreign ministry said in a statement.

Trump adviser Kellyanne Conway told pool reporters in the lobby of Trump Tower on Sunday morning that Taiwan President Tai Ing-wen called Trump.

“He received a phone call. He received a congratulatory phone call. It was brief. And he also recognizes that we currently have a president of the United States and a commander-in-chief until Jan. 20,” she said, according to the pool report.

Trump criticized China throughout his presidential campaign, arguing that trade deals have hurt American jobs and workers.
