BEIJING (Reuters) - North Korea leader Kim Jong Un told an envoy of Chinese president Xi Jinping that North Korea is upholding the denuclearisation agreement it reached with the United States this year, China’s state broadcaster said.

Chinese parliament chief Li Zhanshu, who is in Pyongyang for celebrations marking 70 years since the founding of North Korea, was told by Kim that North Korea hopes the United States keeps to its side of the agreement, Chinese state broadcaster CCTV reported.

Kim met U.S. President Donald Trump in June and agreed to “work toward the complete denuclearisation of the Korean peninsula”, but negotiations appear to have stalled since then, with both sides increasingly critical of each other over a lack of progress.
