The Sungai Tujoh area has been long claimed by the sultan of Brunei to constitute a part of the sultanate. It was divided in 1882, when the
then sultan ceded the basin of the Baram to the
White Rajah of
Sarawak, an area of some , on condition of a perpetual annual payment of 6000 dollars. The border was delineated in 1958 by the
United Kingdom who then had sovereignty over the
colony of Sarawak and was responsible for the external relations of the
protectorate of Brunei. An immigration post was built in the 1960s to control the movement of goods and people between
Miri and points west in Sarawak with Brunei. In 2003,
ASEAN Bridge was constructed across the
Baram River, connecting the city of Miri to Malaysian ICQS complex in Sungai Tujoh. Initially, it was a toll bridge. The bridge become toll-free in 2015. The frequent traveller's card (FTC) was first implemented in 2005 at Sungai Tujoh. This enables residents from both countries to use their Mykad/Smart IC as a legal document for travel between the two countries instead of an international
passport. As at December 2013 the FTC is no longer accepted. ==Transport==
