On October 30, Mr. Xi Jinping attended the Asia-Pacific Economic Cooperation (APEC) Summit in South Korea, where he had a bilateral meeting with US President Donald Trump at Gimhae air base in Busan.
The leaders of the world's two largest economies discussed a series of topics, from soybeans, fentanyl to rare earth minerals and high-end computer chips.
In addition to the tense diplomatic exchanges, the photos just released by the White House recorded a rare, natural moment between the two leaders.
In a room full of diplomats wearing vests, Mr. Trump was seen reaching over the negotiation table to show Mr. Tap Can Binh a piece of paper. The content of that document has not been disclosed.

In another photo, the Chinese leader appeared to be smiling brightly, his eyes closed, and Foreign Minister Wang Yi was also smiling. It is unclear whether these photos are in order of time.
On November 1, Chairman Xi Jinping continued to attract attention when he had a laughing conversation with South Korean President Lee Jae Myung on the sidelines of APEC.
At that time, Mr. Tap Can Binh presented President Lee Jae Myung with two Xiaomi (China) phones equipped with screens made by Korean partners. In response, Mr. Lee joked: "Is the transmission line safe?".
Mr. Tap Can Binh burst out laughing, pointed to the two phones and said: "You can check if they have installed spyware." Mr. Lee Jae Myung also laughed and applauded the Chinese leader's words.

These natural moments of Mr. Tap Can Binh attracted great attention, because he is known as a serious, calm person who rarely smiles in public.
Before meeting with President Donald Trump, Chairman Xi Jinping appeared in a very solemn image when giving a speech at the Central Conference of the Communist Party of China.
In early September, Chairman Xi Jinping also presided over a parade to celebrate the 80th anniversary of the Naxiti victory - a major event considered a memorable historical milestone of China.
At that time, the local media could hardly record any moment showing Mr. Tap Can Binh in the evening gown, smiling like at APEC this time.
