US President Donald Trump and Chinese leader Xi Jinping will “probably” meet at the G20 summit next month, AFP reported.

“The presidents will probably meet at the G20 in Buenos Aires,” Trump economic adviser Larry Kudlow said on the Fox News Sunday program.

But he added that trade negotiations with China – with each side imposing a mounting series of tariffs on the other, intensifying fears of a shock to the global economy – had so far been “unsatisfactory.”

“The relationship has not been positive lately,” Kudlow said.

Cui Tiankai, China’s ambassador to the US, expressed similar doubts about the relationship between the world’s two largest economic powers.

Also appearing on Fox, he said China has become frustrated in trade talks because of conflicting signals from the Trump administration. Cui said other ambassadors in Washington shared his frustration.

“They don’t know who was the final decision-maker” in the administration, he said. “Of course, presumably the president would take the final decision. But who is playing what role? It can be very confusing.”
