Cambodian opposition leader Sam Rainsy is facing new charges of "conspiring to falsify public documents, use fake documents and incite chaos", according to summons issued on Friday.
The summons ordered Sam Rainsy, president of the opposition Cambodia National Rescue Party (CNRP), to appear at the Phnom Penh Municipal Court on December 4 for an inquiry, Xinhua news agency reported.
It warned that if he does not show up at the court on the schedule, an arrest warrant will be issued.
The summons came after Sam Rainsy had opposition senator Hong Sok Hour post a fake version of a Cambodia-Vietnam border treaty on his Facebook page in August 2014.
Hong Sok Hour was arrested on August 15 in Phnom Penh on the charges of falsifying public documents, using fake documents, and inciting chaos to social security. He could face up to 17 years in jail if convicted.
Sam Rainsy is currently in self-imposed exile to avoid a two-year prison sentence over defamation charges.
Sam Rainsy, who also holds French citizenship, returned to Cambodia ahead of the July 2013 national election after receiving a royal pardon from King Norodom Sihamoni. He had fled the country in 2009 to avoid an 11-year prison sentence over the charges of removing border poles and publishing a false map of the border with Vietnam. The pardon at that time was not included the defamation conviction.
