Sarawak is one of the four original partners of the Federation of Malaysia, alongside Sabah, Singapore (which left in 1965), and the Federation of Malaya. This partnership was established under the Malaysia Agreement 1963 (MA63). However, the validity and benefits of MA63 have been frequently questioned and challenged. Notably, during the signing of MA63, Sabah and Sarawak were British colonies, while the Federation of Malaya was an independent country.
