US President Donald Trump visits China from November 8 to 10, during which he holds his third face-to-face meeting with Chinese President Xi Jinping.

The first in-person meeting between Xi and Trump, which took place at the Mar-a-Lago resort in Florida on April 6-7, was described as "positive and fruitful" by Chinese Foreign Minister Wang Yi.

Trump said he developed an "outstanding" relationship with Xi and the two countries made "tremendous progress" in bilateral ties.

The two sides announced the establishment of four high-level mechanisms for dialogue and cooperation on diplomacy and security, the economy, law enforcement and cyber security, as well as social and people-to-people exchanges.

Xi and Trump exchanged views on the Korean Peninsula, and the Chinese president called on the two countries to properly address differences and sensitive issues. Trump also accepted an invitation from Xi to visit China.

The leaders met again on July 8 at the G20 Summit in Hamburg, and had an in-depth exchange of views regarding the Democratic People's Republic of Korea (DPRK) nuclear issue.

Xi and Trump spoke by phone on February 10, April 12, April 24, July 3, August 12, September 6, September 18 and October 25 respectively.

In their first phone conversation after Trump's inauguration, Xi stressed that the one-China policy is the political basis of China-US relations and Trump reiterated his administration's adherence to the principle.

As tensions on the Korean Peninsula rose, many of the later Xi-Trump calls featured communication and coordination about the DPRK crisis. The two leaders also discussed enhancing bilateral relations and details of Trump's planned visit to China.

In their eighth and latest phone call, Trump congratulated Xi on being re-elected general secretary of the Central Committee of the Communist Party of China (CPC).

In Trump's 33 tweets referencing China, the DPRK and trade featured most frequently. He mentioned the DPRK in 18 tweets and US trade or currency policies toward China in 10 tweets. Seven of his tweets referred to both the DPRK and trade.

"Spoke to President Xi of China to congratulate him on his extraordinary elevation. Also discussed NoKo [the DPRK] & trade, two very important subjects!" Trump tweeted on October 25.

Trump sometimes tried to use the DPRK issue as a bargaining chip in trade talks with China. For example, he accused China of not doing enough to help the US with the DPRK crisis in a pair of tweets on July 29, while also threatening to take a tougher stance on trade.

China has repeatedly stressed that while it is committed to the denuclearization of the Korean Peninsula, it does not hold the key to solving the issue.

US President Donald Trump started his first tour of East Asia with a round of golf in Japan on November 5, teeing off alongside Prime Minister Shinzo Abe.

The two leaders seem to enjoy a strong personal relationship that goes beyond the longstanding bilateral partnership. Six of Trump's 13 tweets about Japan have referenced "wonderful couple" Shinzo and Akie Abe's stay in the president's "winter White House" – the Mar-a-Lago resort in Florida.

November's Trump-Abe meeting, the fifth since the US president assumed office in January, will reaffirm the longstanding alliance and renew the commitment to coping with the threat from the Democratic People's Republic of Korea (DPRK), the White House said ahead of Trump's arrival.

Since Trump's inauguration, the leaders have met in person four times: at the Mar-a-Lago resort, the Taormina G7 Summit in Italy, the G20 Summit in Hamburg, and a UN General Assembly session in New York.

Trump and Abe had a "great time" golfing at the Mar-a-Lago resort, according to the US president, who tweeted: "Japan is very well represented!" In November, the leaders are expected play a few holes with Japanese golfer Hideki Matsuyama, the world’s No.3 ranked pro.

Abe has been described as Trump's "phone buddy": the men have called one another 14 times since January, more often than Abe and former President Barack Obama in the latter's entire second term.

The countries' trade relationship is a big issue, but there's no doubt the DPRK nuclear crisis has dominated the chats. Of the 14 phone calls, the DPRK cropped up in 12.

The leaders had a 40-minute phone conversation after the DPRK launched a missile that flew over Japan in August. Trump assured Abe that the US, as an ally, was 100 percent with Japan.

Trump phoned Abe twice on September 3, once before and once after Pyongyang conducted its sixth nuclear test.

Two days later, Trump tweeted that the US would sell Japan and South Korea a "substantially increased amount of highly sophisticated" military equipment, as the US and its allies sought to counter the threat from the DPRK.

US President Donald Trump was the first foreign leader to call Moon Jae-in to congratulate him on becoming South Korean president on May 10.

During their first phone conversation, Trump made two points clear. He told Moon that South Korea and the US are "not just good allies, but great allies" and stressed that the Democratic People's Republic of Korea (DPRK) nuclear issue is a difficult problem that can be resolved.

The DPRK has topped the agenda in every communication between the two leaders since. Trump has regularly tweeted about the "highlights" of those meetings or phone calls.

Four later phone conversations were dominated by the DPRK's missile and nuclear tests, and featured agreement to increase pressure on Pyongyang (Trump also spoke by phone with Acting President Hwang Kyo-ahn three times).

After their latest phone call on September 17, Trump tweeted: "I spoke with President Moon of South Korea last night. Asked him how Rocket Man is doing."

Trump and Moon have held face-to-face talks three times since the South Korean president was sworn into office.

Moon's first overseas trip as president was to Washington. Trump tweeted twice about his first in-person meeting with Moon, praising a "very good" conversation and hinting the two sides could renegotiate a five-year-old free trade deal – it was later announced that talks on amending the agreement would take place.

Trump also met Moon at the G20 Summit in Hamburg, together with Japanese Prime Minister Shinzo Abe. In a joint statement, the three leaders said they would "press for the early adoption of a new UN Security Council resolution with additional sanctions to demonstrate to the DPRK that there are serious consequences for its destabilizing, provocative, and escalatory actions."

"It was a great privilege to meet with President Moon of South Korea," Trump tweeted after his latest meeting with Moon, in New York during the 72nd UN General Assembly. The two sides committed to strengthening their defensive cooperation and agreed to further discussions during Trump's South Korea visit in November.
