Philippine President Rodrigo Duterte has arrived on a state visit to Cambodia, where a meeting with Prime Minister Hun Sen will bring together two Southeast Asian leaders known for their tough-guy approach to governing.

The two leaders will witness the signing of memoranda of understanding on cooperation in sports and combating transnational crime. Their talks are also expected to touch on the South China Sea, where the Philippines has a territorial dispute with China, which is Cambodia's closest ally.

Duterte, who been president since June, has been directing a war on illegal drugs which has resulted in the deaths of thousands of suspected drug dealers and users. Hun Sen has led his country for three decades of authoritarian rule by directing violence and intimidation at his political opponents.
