Donald Trump’s North Korea warning sparks concern in Asia

Mr Graham said that Chinese diplomats felt they had the upper hand ahead of this week’s summit meeting between Chinese president Xi Jinping and Mr Trump because of the US president's lack of foreign policy experience.

“That inexperience raises the question of whether it's prudent to engage at such a high level with China so early on, when the basic elements of US Asia policy are yet to be sorted and appear incoherent,” he added.
