US President Donald Trump and China's President Xi Jinping attend a bilateral meeting on the sidelines of the G20 Summit in Osaka on June 29, 2019.

President Donald Trump on Wednesday tweeted that he will delay increasing tariffs on $250 billion worth of Chinese goods from Oct. 1 to Oct. 15 as a "gesture of good will" to China.

Trump said the postponement came "at the request of the Vice Premier of China, Liu He, and due to the fact that the People's Republic of China will be celebrating their 70th Anniversary."

The tariffs were set to increase to 30% from 25% on the goods. He is set to be in Washington for talks in early October.

U.S. stock futures jumped more than 0.5% percent after news of the delay. The Dow is poised to open up 150+ points on Thursday.

President Trump wanted to double tariff rates on Chinese goods last month after Beijing's latest retaliation in the trade war before settling on a smaller increase, sources told CNBC. He was outraged after he learned Aug. 23 that China had formalized plans to slap duties on $75 billion in U.S. products in response to new tariffs from Washington on Sept. 1.

Treasury Secretary Steven Mnuchin and U.S. Trade Representative Robert Lighthizer then enlisted multiple CEOs to call Trump and warn him about the impact such a move would have on the stock market and the economy.

He settled on a 5% hike in tariff rates on about $550 billion in Chinese products, which he announced in an Aug. 23 tweet after the market close.

In the following days, both Mnuchin and White House press secretary Stephanie Grisham said Trump's only regret was not raising tariffs higher.

Earlier this month, Mnuchin said the U.S. and China have a "conceptual" agreement on enforcement concerns, emphasizing positive progress already made in trade talks, which are set to resume at high levels next month.

"I think the enforcement area we at least have a conceptual, an agreement on," Mnuchin told Fox Business Network.

He also had a warning: President Donald Trump has no problem keeping heavy tariffs on Beijing if a deal can't be reached.
