History
Prior to full independence in 1984, Brunei was a British protectorate, with international representation being the responsibility of the United Kingdom, in which its interests were represented by the "Brunei Government Agency" in London. A Government Agency was also established in Kuala Lumpur, Malaysia, at the end of 1981. This was later renamed the Brunei Commission. When Brunei joined the Commonwealth on independence, these became known as High Commissions. In 1983, shortly before independence, the country established a Government Agency in Manila, in the Philippines, which was later upgraded to an Embassy.
