The presidents of China and the United States met on Monday.

When the presidents of China and the United States met on Monday, they talked about not only world and bilateral issues, but also family and even jokes.

In their more than one hour and half meeting on Monday, President Xi Jinping said "Before arriving in the Netherlands, my wife and I met and had pleasant talks with your wife Michelle, your mother-in-law Ms Robinson and daughters Malia and Sasha.

Xi even joked that when their meeting in Beijing last week was over, Michelle Obama had asked him to "formally convey her best regards" to (Barack) Obama.

The US first lady arrived in Beijing on Thursday for a weeklong tour of the country.

Obama thanked Xi and his wife "for being such a gracious host to Michelle for her first visit to China".

Obama also joked that "She also played some table tennis, although I think this was not the high level ping pong diplomacy that we saw in the past."
