Trump announced the pair of meetings to reporters in the Oval office on Monday afternoon. Earlier that morning, Russian newspaper Kommersant reported that Washington had requested a meeting with Putin, and was awaiting the Kremlin’s response.

The meeting with Putin comes at a time of strained relations between Washington and Moscow. Although Trump and Putin discussed a range of geopolitical issues in an hour-long phone call less than two weeks ago, US Secretary of State Mike Pompeo and Russian Foreign Minister Sergey Lavrov are expected to clash over the ongoing Venezuela crisis and Iran’s nuclear program when they meet in Sochi on Tuesday.

Pompeo and Lavrov will likely also discuss the US’ recent withdrawal from the Intermediate-Range Nuclear Forces (INF) treaty, and the US’ recent deployment of a carrier group to the Persian Gulf, under the auspices of countering what they claim is Iranian aggression.

Trump’s meeting with Xi will most likely focus on trade. In the latest escalation of the countries’ tit-for-tat trade war, China announced on Monday it would hike tariffs on $60 billion in American goods as high as 25 percent.

That move comes after the White House increased tariffs on $200 billion worth of Chinese imports from 10 percent to 25 percent last Friday.
