Foreign Minister Hor Namhong is set to visit Australia in September ahead of a December visit by Prime Minister Hun Sen to discuss, among other things, the controversial refugee deal between the two countries, the ministry announced yesterday.

The announcement came after a bilateral meeting between Namhong and his Australian counterpart Julia Bishop on the sidelines of the 2015 ASEAN Foreign Ministers Meeting in Malaysia last week.

“Both parties have discussed the implementation of the [memorandum of understanding] on the refugees, which was signed in September 2014, and both prime ministers of the two countries will discuss it further on the visit of Samdech Techo Prime Minister [Hun Sen],” the statement reads.

Four refugees – three Iranians and an ethnic Rohingya from Myanmar – arrived in June following the agreement, which was lambasted in both Cambodia and Australia by observers.

In a separate bilateral meeting with his Vietnamese counterpart, Pham Binh Minh, Namhong once again requested that Vietnam stop all activities along the undemarcated portions of the countries’ shared border, and that it fill in several ponds thought to have been dug in Ratanakkiri province.

“The Vietnamese foreign minister has agreed to send a technical team to inspect the site and to allow the joint border commission to continue discussing for further resolution,” the statement reads.
