Foreign affairs ministers from Myanmar and Bangladesh have exchanged instruments of ratification of the agreement on the demarcation of the land boundary north of the Naf River, China's Xinhua news agency reported Myanmar's foreign ministry as saying late Thursday.

The agreement was signed in 1998.

Officials from both sides also signed the Supplementary Protocol of the Naf River Boundary which was agreed in 2007.

Myanmar and Bangladesh carried out boundary survey and demarcation on the inland boundary of the northern part of the Naf River in 1984.
