Summary:

In 1982 Cambodia and Vietnam concluded an agreement that integrated the baselines and resolved territorial disputes over several islands. The agreement also established an area of ‘historical waters of the two countries placed under the juridical regime of their internal waters., called ‘Joint Historic Waters Area or JHWA’ to engage in cooperation.

The agreement stipulated that the two countries would hold, “at a suitable time”, negotiations to determine the maritime frontier in the historic waters area and that the exploitation of the zone would be decided by ‘common agreement.’

The extent the MOU has been implemented to date is unclear.
