U.S. President Donald Trump on Thursday signaled a potential end to the tit-for-tat tariff hikes between the U.S. and China that shocked markets, and that a deal over the fate of social media platform TikTok may have to wait.

“I don’t want them to go higher because at a certain point you make it where people don’t buy,” Trump told reporters about tariffs at the White House, Reuters reported.

“So, I may not want to go higher or I may not want to even go up to that level. I may want to go to less because you know you want people to buy and, at a certain point, people aren’t gonna buy.”

Trump’s comments further pointed to a diminished appetite for sharply higher across-the-board tariffs on dozens of countries after markets reacted violently to their introduction on April 2.

The Republican president slapped 10% tariffs on most goods entering the country but delayed the implementation of higher levies, pending negotiations.

Still, he hiked rates on Chinese imports, now totaling 145%, after Beijing retaliated with its own counter-measures. Last week, China said “will not respond” to a “numbers game with tariffs,” its own signal that across-the-board rates would not rise further.

Trump said China had been in touch since the imposition of tariffs and expressed optimism that they could reach a deal.

While the two sides are in touch, sources told Reuters that free-flowing, high-level exchanges of the sorts that would lead to a deal have largely been absent.

Speaking with reporters, Trump repeatedly declined to specify the nature of talks between the countries or whether they directly included Chinese President Xi Jinping.

Trump has repeatedly extended a legal deadline for China-based ByteDance to divest the U.S. assets of the short video app used by 170 million Americans. On Thursday, he said a spin-off deal would likely wait until the trade issue is settled.

“We have a deal for TikTok, but it’ll be subject to China so we’ll just delay the deal ’til this thing works out one way or the other,” Trump said.

President Donald Trump met with his top national security aides on Tuesday to discuss Iran’s nuclear program ahead of a second meeting between U.S. and Iranian officials on Saturday, sources said.

U.S. special envoy Steve Witkoff is to meet his Iranian counterpart on Saturday, a session currently scheduled to be held in Oman. Trump spoke to the sultan of Oman, Haitham bin Tariq, about Oman’s mediation role between Washington and Tehran.

A White House official confirmed the White House Situation Room meeting on Iran and said the location was not unusual since Trump gets briefed there regularly to take advantage of the chamber’s secure setting.

A second source briefed on the meeting said Trump and his top aides discussed the Iran talks and next steps. U.S. officials have been working on a framework for a potential nuclear deal.

Trump has threatened military action against Iran if it does not give up its nuclear program while also stressing the need for diplomacy and negotiations.

White House press secretary Karoline Leavitt told reporters Trump’s bottom line in the talks, which included an initial session last Saturday, is he wanted to use negotiations to ensure Iran does not obtain a nuclear weapon.

Trump and the Omani leader also discussed ongoing U.S. operations against Yemen’s Houthis, she said.

“The maximum pressure campaign on Iran continues,” Leavitt said at a press briefing. “The president has made it clear he wants to see dialogue and discussion with Iran, while making his directive about Iran never being able to obtain a nuclear weapon quite clear.”

She added that he had “emphasized” this directive during the call with Sultan Haitham.

Both sides described last weekend’s U.S.-Iran talks in Oman as positive.

Trump has restored a “maximum pressure” campaign on Tehran since February, after he ditched a 2015 nuclear pact between Iran and six world powers during his first term and reimposed crippling sanctions on the Islamic Republic.

Iran’s nuclear program has leaped forward since then. The two countries held indirect talks during former President Joe Biden’s term but made little, if any progress.

Iran’s clerical rulers have publicly said that demands such as dismantling the country’s peaceful nuclear program or its conventional missile capabilities were off the table.

President Donald Trump said on Monday he believes Iran is intentionally delaying a nuclear deal with the United States and that it must abandon any drive for a nuclear weapon or face a possible military strike on Tehran’s atomic facilities, Reuters reported.

“I think they’re tapping us along,” Trump told reporters after U.S. special envoy Steve Witkoff met in Oman on Saturday with a senior Iranian official.

Both Iran and the United States said on Saturday that they held “positive” and “constructive” talks in Oman. A second round is scheduled for Saturday, and a source briefed on the planning said the meeting was likely to be held in Rome.

The source, speaking to Reuters on the condition of anonymity, said the discussions are aimed at exploring what is possible, including a broad framework of what a potential deal would look like.

“Iran has to get rid of the concept of a nuclear weapon. They cannot have a nuclear weapon,” Trump said.

Asked if U.S. options for a response include a military strike on Tehran’s nuclear facilities, Trump said: “Of course it does.”

Trump said the Iranians need to move fast to avoid a harsh response because “they’re fairly close” to developing a nuclear weapon.

The U.S. and Iran held indirect talks during former President Joe Biden’s term but they made little, if any progress. The last known direct negotiations between the two governments were under then-President Barack Obama, who spearheaded the 2015 international nuclear deal that Trump later abandoned, read the report.
