Cambodia’s Prime Minister, Hun Manet, has nominated U.S. President Donald Trump for the Nobel Peace Prize, praising his "extraordinary statesmanship" in resolving a border dispute between Cambodia and Thailand.

Thailand has turned down offers of third-party mediation to end its escalating conflict with Cambodia, saying it prefers to resolve the crisis through direct bilateral talks.

Thailand has closed its border to almost all travelers from Cambodia as diplomatic tensions escalate over a territorial dispute between the two neighboring Southeast Asian countries.

Cambodia announced on Monday that it will file a complaint with the International Court of Justice (ICJ) regarding ongoing border disputes with Thailand.
