Royalist FUNCINPEC Secretary Nhek Bun Chhay led 6 other party members Friday to Malaysia, say party officials, to see FUNCINPEC's president Prince Norodom Ranariddh.
The party's internal issues are expected to be discussed at the meeting.
The royalist party experienced internal conflicts after the prince remained abroad since he left his position as National Assembly president.
Prince Ranariddh's spokesman Chea Chanbaribo says that the meeting will cover party reforms to local leadership.
Prince Ranariddh suggests the party secretariat to officially announce the names of those who left the party.
In another development, a government high ranking official criticizes opposition party leader for his plan to conduct a demonstration next month on land conflict, saying it is a way of pushing a political profession too far.
Prime Minister Hun Sen's adviser Om Yentieng says that such demonstration will not be successful, but rather make the people face more difficulties.
In another development, government spokesman Khieu Kanharith criticizes the Journalists Without Borders for pushing the arrest of Prime Minister Hun Sen's nephew Hun To for threats against Sralanh Khmer newspaper chief You saravuth for printing articles alleging land grabbing.
