than the states of Peninsular Malaysia. Because of its natural resources, Sarawak specialises in the export of oil and gas, timber and oil palms, but also possesses strong manufacturing, energy and tourism sectors. It is ethnically, culturally, and linguistically diverse; major ethnic groups including Iban, Malay, Chinese, Melanau, Bidayuh and Orang Ulu.

Chinese ceramics dating to the Tang and Song dynasties (8th to 13th century AD, respectively) found at Santubong (near Kuching) hint at its significance as a seaport. The settlement known as Vijayapura was a vassal-state to the Buddhist Srivijaya empire and was thought to be located in Borneo's Northwest which flourished in the 7th Century. This alternate Srivijaya referring to Brunei, was known to Arabic sources as "Sribuza". The Arabic author Al Ya'akubi writing in 800 recorded that the kingdom of Musa (Muja, which is old Brunei) was in alliance with the kingdom of Mayd (Either Ma-i or Madja-as in the Philippines), against the
