After Donald Trump's flip-flop on the one-China policy during his phone call with Chinese President Xi Jinping early this month, the next big question for diplomatic pundits is when and where the two leaders will meet in person.
Several Chinese sources said suggestions have been made that the first meeting between the two leaders will be on the sidelines of the G20 summit in Germany in July.
"Beijing is in contact with Trump's team over the possibility of a bilateral meeting on the sidelines of the G20 summit in Hamburg in July," one of the sources said, adding that Washington had also expressed similar intentions.

Diplomatic pundits also believe the G20 summit is likely to be the first opportunity for Xi and Trump to meet, even though there are still uncertainties over whether the US president will attend as his new administration appears sceptical of multinational political gatherings.
Yuan Peng, vice-president of the China Institute of Contemporary International Relations, said a personal meeting between the two leaders would be essential to set the tone and direction for their relationship and to establish new ways of communication.
"This is the most urgent thing for both countries to work at in the near future," he said.
