The People's Action Party (PAP), the dominant political party in Singapore, and United Malays National Organisation (UMNO), the dominant political party in Malaysia, had two differing competing political ideologies. The PAP, led by Lee Kuan Yew, adopted non-communal politics whereby it called for equality for all regardless of race or religion. By contrast, UMNO, led by Tunku Abdul Rahman, advocated for the provision of special rights and privileges for the "bumiputeras" (indigenous Malays in Malaysia); meant as a form of affirmative action as the Straits Chinese had traditionally better economic affluence and the Malays tended to be poorer. As part of a "cold peace" between the two parties, Tunku Abdul Rahman assured Lee that the Alliance Party would not get involved in Singapore’s domestic politics as long as the PAP confined its political role to Singapore.
