Thailand on Tuesday denied entry to controversial Cambodian opposition leader Sam Rainsy over concerns he would engage in political campaigning in the neighboring Southeast Asian nation. Foreign Ministry spokesman Manasavi Sridasopol said on Wednesday that Sam Rainsy will not be allowed to enter the country until a general election in Cambodia is over. Sam Rainsy is living in self-imposed exile to avoid 12 years in prison from convictions widely seen as politically motivated. Thailand has denied visas to several visitors, fearing the trips could upset ties with other countries, including the Dalai Lama’s sister.
