People's Action Party–United Malays National Organisation relations

The People's Action Party (PAP) of Singapore and the United Malays National Organisation (UMNO) of Malaysia have a complex history of bilateral relations, marked by periods of cooperation and tension. The two parties have maintained a close relationship since Singapore's independence in 1965, with the PAP often seeking UMNO's support on regional issues. However, their ties have also been strained by disagreements over issues such as immigration and economic policies.
