Trump pushed back on China after Beijing's Foreign Affairs Ministry called the administration's assertions that tariff talks are happening "fake news."

"Well, they had a meeting this morning, so I can't tell you," Trump began to say before a reporter pressed him on who was the "they" he referred to.

"It doesn't matter who 'they' is. We may reveal it later, but they had meetings this morning, and we've been meeting with China," Trump said, before going on to criticize the reporter who asked the question.

Trump suggested in a Truth Social post on Thursday that Boeing should default on China following its decision to halt deliveries and return planes due to tariffs.

"This is just a small example of what China has done to the USA, for years," he wrote.

The president also continued to allege fentanyl is pouring into the United States from China, Mexico and Canada.

"[I]t better stop, NOW!" he posted.

The administration is considering possible exceptions for some Chinese auto parts, sources told ABC News.

While no final decision has been made, the administration is examining streamlining overlap between auto Section 232 tariffs and the steel, aluminum, and fentanyl tariffs.

"No final decisions have been made by the White House on any potential changes to the auto tariffs," White House spokesperson Kush Desai said.

A Chinese official on Thursday said that claims that Washington and Beijing are in active talks about tariffs were "all fake news."

Ministry of Foreign Affairs spokesperson Guo Jiakun said that the two sides have not consulted or negotiated on tariffs at all, but signaled that Beijing would be open to talks on an equal and reciprocal footing.
