Trump admin live updates: Trump says Hamas will release hostage Edan Alexander

In a statement posted after Trump called for Ukrainian President Volodymyr Zelenskyy to attend talks in Turkey with Russia on Thursday, Zelenskyy said he would be there.

"I will be waiting for Putin in Türkiye on Thursday. Personally," Zelenskyy said.

Zelenskyy's office confirmed to ABC News that Zelenskyy will travel to Istanbul.

Zelenskyy again called for Russian President Vladimir Putin to accept a ceasefire proposal before any talks take place, but Putin has dismissed a ceasefire.

The White House communications office sent a news release Sunday announcing that a trade deal with the Chinese has been reached, but it offers no details, and the Chinese have yet to address it.

The release points to U.S. Trade Representative Jamieson Greer's on-camera statement today in Geneva, where he said, "We’re confident that the deal we struck with our Chinese partners will help us to work toward resolving that national emergency.”

Treasury Secretary Scott Bessent announced "substantial progress" had been made with the Chinese but stopped short of touting a full deal.

He also said that there would be a full briefing on Monday.

China has not yet commented on the negotiations.

As of now the trade embargo is still in effect. The White House has not yet announced that the 145% tariff will be altered.

But sources in the administration told ABC News this appears to be a significant step toward that possible action.

Trump urged Ukraine to meet with Russia in Turkey despite Vladimir Putin dismissing the idea of a 30-day ceasefire.

"President Putin of Russia doesn’t want to have a Cease Fire Agreement with Ukraine, but rather wants to meet on Thursday, in Turkey, to negotiate a possible end to the BLOODBATH. Ukraine should agree to this, IMMEDIATELY. At least they will be able to determine whether or not a deal is possible, and if it is not, European leaders, and the U.S., will know where everything stands, and can proceed accordingly!" Trump posted on his Truth Social platform.

Putin has offered to hold direct talks with Ukraine in Turkey on Thursday, but Zelenskyy said that Ukraine is “ready to meet,” but not without a ceasefire starting Monday.

Oksana Markarova, Ukraine’s ambassador to the U.S., told ABC News’ “This Week” that “President Zelenskyy today already said that, yes, Ukraine is ready to negotiate. But he put a special emphasis on ceasefire. The idea that both he and President Trump strongly supports.”
