If the trade war between China and the United States is a game of high-stakes brinkmanship, it is currently a game that Beijing is not willing to play.

Faced with growing claims by President Trump and administration officials that the two countries are engaged in talks and that a deal could be reached in a matter of weeks, China’s Foreign Ministry pushed back forcefully on Friday by posting on X: “China and the U.S. are NOT having any consultation or negotiation. The U.S. should stop creating confusion.”

The post came hours after a foreign ministry spokesman, Guo Jiakun, said the United States was “misleading the public.” A day earlier, Mr. Guo called the rumors of talks “fake news.”

The response was the latest sign that China’s top leader, Xi Jinping, intends to hold firm in his standoff with Mr. Trump, sensing that his position is strengthening. Beijing is betting that it can stomach the pain of a trade war better than the Trump administration can because of U.S. political pressure and volatility on Wall Street, analysts say.

“The Chinese are not eager to climb down the ladder,” said Yun Sun, the director of the China program at the Stimson Center in Washington. “They see Trump as wanting to climb down and are happy to let him stew in his own juice.”

Ms. Sun said Beijing will not come to the negotiation table without any U.S. concessions or a good-will gesture. That could include scaling back tariffs, or making clear that Mr. Trump is reaching out to Mr. Xi first.
