The Thai authorities accused an adviser to Hun Sen of hiring the gunman who killed a former Cambodian opposition figure in Bangkok last week.

Lim Kimya was gunned down by a motorcyclist as he arrived in Bangkok by bus from Cambodia with his French wife.

The victim was Lim Kimya, a 73-year-old former parliamentarian from the main Cambodian opposition party, the CNRP, which was banned in 2017. He had been hit in the chest by two bullets, according to the Thai police. He had just arrived in Bangkok with his wife on a bus from Cambodia.

The killing of a former Cambodian politician stoked safety fears that Thailand is no refuge for those fleeing autocracy.

For government critics in Southeast Asia, fleeing abroad does not necessarily mean safety. Thailand is growing particularly dangerous for foreigners seeking protection.

Cambodian Prime Minister Hun Manet denied on Monday his government and father, former leader Hun Sen, were involved in the killing of an opposition politician in downtown Bangkok this month.

Lim Kimya, a French-Cambodian citizen who worked as a French bureaucrat before entering the Cambodian parliament for the CNRP in 2013, was shot twice and died near Bangkok’s popular tourist center of Khao San Road on the evening of Jan. 7.

The Cambodian case comes as Thailand is already under scrutiny over the case of 48 Uyghurs, detained in Bangkok for almost a decade, amid reports Thailand is preparing to send them back to China, and the case of a Vietnamese activist who Hanoi wants to extradite and jail for terrorism.

Thai nationalists are threatening to unleash mass street protests to prevent the government making any concessions over its long-standing territorial disputes with Cambodia.

Like the other Cambodian national wanted in connection with the murder, Ly Ratanakrasmey, 43, has links to the Cambodian government.

Lim Kimya, 74, a former member of parliament for the banned opposition Cambodia National Rescue Party (CNRP), was gunned down in Bangkok on Jan. 7. The suspected gunman, Aekaluck Paenoi, a former Thai Marine, was arrested the day after in Cambodia’s Battambang province and was extradited to Thailand on Jan. 11.
