China remains committed to the goal of denuclearizing the Korean Peninsula, firmly maintains the international nuclear nonproliferation mechanism and resolutely champions peace and stability in Northeast Asia, President Xi Jinping has said.

Xi made the remarks in a phone conversation with British Prime Minister Theresa May on Monday when they exchanged views on the situation on the peninsula.

The peninsula issue should be resolved through peaceful means, including dialogue and consultation, and this requires the joint efforts of the international community, Xi said.

Xi noted that both China and Britain are permanent members of the United Nations Security Council, and they have duties and obligations to deal with relevant issues with the perspective of maintaining regional and world peace.

Xi said it is hoped Britain stays committed to promoting peace and talks and playing a constructive role in easing the tension and resuming dialogues.

May said Britain is committed to maintaining international and regional peace and stability and is committed to the peaceful settlement of the Korean Peninsula nuclear issue.

The United Kingdom attaches importance to China's great influence in resolving the peninsula issue, it appreciates the efforts made by China and it is ready to strengthen communication and coordination with China, she added.

Kerry Brown, a professor of Chinese studies at King's College London and director of its Lau China Institute, said it's in the UK's interest to calm the situation, and China showing leadership in achieving this is important.

Speaking on China-UK ties, Xi noted that this year marks the 45th anniversary of the establishment of bilateral ambassador-level diplomatic relations.

The two sides should maintain high-level exchanges, promote dialogue mechanisms in various fields, and maintain the strong momentum of bilateral trade as well as cultural exchanges and cooperation, Xi noted.

Both countries should deepen the synergy of their development strategies in the framework of the Belt and Road Initiative, and strengthen coordination in championing world peace and development, Xi said.

The prosperity, stability and openness of both Britain and the European Union serve the interests of all parties, and China is ready to promote the development of both China-UK and China-EU ties, Xi said.

May said Britain is ready to work with China to have closer high-level exchanges, make good use of their strategic dialogue, deepen cooperation in areas such as economy and trade, security and culture, and promote the development of EU-China relations.
