Chinese President Xi Jinping has told North Korean leader Kim Jong Un he hopes Pyongyang and Washington can fully implement the outcomes of last week’s nuclear summit.

State broadcaster CCTV said Mr Xi told Mr Kim that through the “concerted efforts of the relevant countries”, negotiations regarding issues on the Korean peninsula are back on track and the overall situation is moving in the direction of peace and stability.

The summit last week between Mr Kim and US President Donald Trump in Singapore marked an “important step toward the political solution of the Korean peninsula nuclear issue”, Mr Xi was quoted as saying in the meeting at the Great Hall of the People in central Beijing.

Mr Xi said China hopes North Korea and the US can “implement well the outcomes achieved at the summit”.

He said China would “as always play a constructive role” in the process.

In a joint statement at last week’s summit, Mr Kim pledged to work towards the denuclearisation of the Korean peninsula in exchange for US security guarantees.

Mr Trump also agreed to suspend military exercises with South Korea in what was seen as a major win for North Korea and its chief allies China and Russia.
