It was a day after a general election in which his Cambodian People’s Party (CPP) declared victory but one which rights groups said was neither free nor fair.
The White House said it would consider steps, including an expansion of visa restrictions placed on some Cambodian government members, in response to “flawed elections” in which there was no significant challenger to Hun Sen.
CPP spokesman Sok Eysan said on Sunday the party won an estimated 100 out of 125 parliamentary seats. The DAP news, a pro-government website, said later the CPP had won 114 seats. Two other parties, the royalist Funcinpec party and the League for Democracy Party, won five and six seats respectively.
More than 82 percent of those registered to vote cast a ballot, according to the National Election Commission. Turnout was 90 percent in the 2017 local election and 69.61 percent in the previous general election in 2013.
Critics say the election was a backward step for democracy in Cambodia following the dissolution last year of the main opposition Cambodian National Rescue Party (CNRP) and the jailing of its leader, Kem Sokha, on treason charges.
Former CNRP president Sam Rainsy, who lives in exile, said the election was a “hollow” victory for Hun Sen, a former Khmer Rouge commander who has ruled Cambodia for nearly 33 years.
The United States has imposed visa curbs on some Cambodian government members over a crackdown on critics and levied sanctions in June on a high-ranking official close to Hun Sen.
The European Union has threatened Cambodia with economic sanctions.
White House Press Secretary Sarah Sanders said in a statement Sunday’s vote “failed to represent the will of the Cambodian people”.
“The flawed elections, which excluded the country’s principal opposition party, represents the most significant setback yet to the democratic system enshrined in Cambodia’s constitution,” Sanders said, adding that the election campaign was marred by threats from national and local leaders.
“The United States will consider additional steps to respond to the elections and other recent setbacks to democracy and human rights in Cambodia, including a significant expansion of the visa restrictions announced on December 6, 2017,” she said.
Many polling stations in the center of the capital, Phnom Penh, appeared quiet on Sunday. Polling stations Reuters visited in the city were less than bustling and some voters said they voted because not doing so would land them in trouble.
The opposition CNRP had called on voters to boycott the election but authorities warned anyone doing so would be seen as a traitor.
“It is same same,” said one tuk-tuk driver in Phnom Penh on Monday in reaction to the election result.
“Hun Sen again,” said the driver, who did not vote and who declined to be named because he feared for his safety.
