A beaming US President Donald Trump hailed his "great success" in talks with Chinese President Xi Jinping in the South Korean city of Busan.
From a deal to reduce tariffs slapped on China for its role in the fentanyl trade to planned cooperation in ending the war in Ukraine, here's what President Trump says he achieved in talks with President Xi:
Fentanyl
The fentanyl trade has long been a sore point in relations between China and the United States: Washington accuses Beijing of turning a blind eye to the illegal trade in the drug, a charge it denies.
Mr Trump hit China with a 20% levy on Chinese imports over complaints about its exports of chemicals used to make fentanyl.
However, he said after the talks in Busan the tariffs would be reduced to 10%, bringing overall US tariffs on Chinese goods to 47%.
Mr Trump said Mr Xi "agreed that he was going to work very hard to stop the flow" of the powerful opioid, which has killed thousands of Americans.
"I believe he's going to work very hard to stop the death that's coming in," President Trump told reporters on Air Force One.
Hill of beans
China retaliated against Mr Trump's fentanyl tariffs with levies against US agricultural products, including soybeans.
More than half of US soybean exports went to China last year, but Beijing halted all orders as the trade dispute deepened.
US farmers have been badly hit by the tariff war and are a key source of domestic political support for President Trump.
Mr Trump said China had now agreed to purchase "tremendous" amounts of soybeans, as well as other farm products.
"That was a very nice gesture," he said.
Rare earths
A strategic field dominated by China that is essential for manufacturing in defence, automobiles and consumer electronics, rare earths were expected to occupy a central role in the Busan talks.
China imposed sweeping export controls on the materials and related technology this month.
Mr Trump swiftly announced retaliatory tariffs of 100% on all Chinese goods, which were originally due to come into effect on Saturday.
But the US leader insisted that "that whole situation, that roadblock is gone now".
"There's no roadblock at all on rare earths, that will hopefully disappear from our vocabulary," he said, without giving details.
Ukraine
The United States and China have also reportedly agreed to cooperate more on seeking an end to the war in Ukraine.
China says it is a neutral party in the conflict, but Ukraine and Western governments have long accused it of providing political and economic support to Russia.
Mr Trump told reporters the subject had come up "very strongly" during his talks with President Xi.
"He's going to help us, and we're going to work together on Ukraine," President Trump said.
Chips
China has ramped up its chip industry to beat the US export restrictions on the critical component used to power artificial intelligence systems.
US chip giant Nvidia has been caught in the middle of that geopolitical tussle.
Nvidia's chips are currently not sold in China due to a combination of Beijing government bans, US national security concerns and ongoing trade tensions.
CEO Jensen Huang has urged the United States to allow the sale of US-made AI chips in China in order to ensure Silicon Valley companies remain a global powerhouse in providing artificial intelligence.
"We did discuss chips," Mr Trump said after meeting Mr Xi, adding that Mr Huang would speak to Beijing about the dispute.
"We're sort of the arbitrator or the referee," Mr Trump said.
Mr Huang is currently in South Korea for the Asia-Pacific Economic Cooperation CEO summit in Gyeongju, which President Xi is also expected to attend.
