the Sarawak Communist Insurgency against the communists. Following the formation of Malaysia, the regiment was absorbed into the Malaysian military forces and is now known as the Royal Ranger Regiment. In 1888, Sarawak, together with neighbouring North Borneo, and Brunei, became British protectorates, and the responsibility for foreign policy was handed over to the British in exchange for military protection. Since the formation of Malaysia, the Malaysian federal government has been solely responsible for foreign policy and military forces in the country. Territorial disputes Several border disputes between Malaysia and its neighbouring countries concern Sarawak. Land and maritime disputes exist with Brunei. In 2009, Malaysian prime minister Abdullah Ahmad Badawi claimed that in a meeting with Sultan of Brunei, Brunei agreed to drop its claim over Limbang.
