Foreign affairs expert Gordon Chang told Hill.TV's "Rising" on Friday that the U.S. has more leverage in its trade talks with China after President Trump Donald John TrumpOmar fires back at Trump over rally remarks: 'This is my country' Pelosi: Trump hurrying to fill SCOTUS seat so he can repeal ObamaCare Trump mocks Biden appearance, mask use ahead of first debate MORE walked away from denuclearization talks with North Korea this week.

Trump announced on Thursday that the U.S. was not willing to fully remove sanctions on North Korea in return for a partial denuclearization of the Korean Peninsula.

“[S]ometimes you have to walk, and this was just one of those times," Trump said.

Chang said Trump's actions in Hanoi, Vietnam, have been monitored by the Chinese in terms of the trade talks.

"Right now, I think the Chinese are saying to themselves, 'look, we're probably going to have to give up more than we had anticipated,' " Chang told hosts Krystal Ball and Mattie Duppler.

"These are really tough negotiations. I'm not so sure you can get the Chinese to agree to change the entire nature of their economy and even their society, but nonetheless, they have a lot [less] leverage today after President Trump walked out of Hanoi."

Chang pointed to comments made by U.S. trade representative Robert Lightizer prior to Trump's summit with North Korean leader Kim Jong Un as showing that China may have thought Trump would “cave” in trade negotiations.

"He said, look, we've got some structural issues we have yet to resolve with China, and I think when the Chinese thought, 'oh, you know, President Trump's going to cave on those,' a lot of people were saying the same thing, and a lot of people were worried," he said.
