Kem Sokha, the leader of the Cambodia National Rescue Party (CNRP), was charged with treason last week, amid allegations of conspiring with a foreign power to overthrow the government.

In all likelihood, the charges mean the imminent dissolution of the main opposition party, leaving the ruling party – the Cambodian People’s Party (CPP) – the only real contender in next year’s general elections.

The charges are the latest in the rolling back of democratic processes in the nation. They also reflect a shift in global democracy.

Destroying democracy

The latest development follows a pattern that has included alleged electoral intimidation in the recent commune elections, media suppression, and increasing threats of violence and conflict should the opposition win.

In the last three weeks, 17 radio providers that gave airtime to the opposition and aired programs produced by the Voice of America and Radio Free Asia – two Washington-based outlets that often include political critique – have had their licences revoked.

Last Monday, The Cambodia Daily, an English-language newspaper renowned for hard-hitting journalism, closed after 24 years, after being hit with an unaudited tax bill of US$6.3 million, with no course of appeal.

In August, the National Democratic Institute’s office in Cambodia was forced to close, and its foreign staff were deported, following alleged infringement of the Law on Associations and Non-governmental Organisations (LANGO). This law was passed earlier this year, severely restricting the rights of civil society actors across the nation.

These actions are largely agreed to be manoeuvres to consolidate the political power of the CPP under the increasingly autocratic rule of Prime Minister Hun Sen, who, following Sokha’s arrest, has declared he will rule for another ten years.

The violence of Hun Sen

My research shows that Cambodian politics has always been a sphere of violence, but that since the 1993 UN-backed elections, it has happened under a veneer of liberal democracy.

According to Human Rights Watch, Hun Sen has the worst human rights record of any “democratic” leader.

Although his party lost the 1993 elections, he forced a coalition, before seizing power after violent clashes in 1997. Elections since then have been plagued by accusations of fraud, corruption and voter intimidation. Hun Sen’s personal bodyguard is implicated in much public violence, including brutal beatings of political opponents.

But these current moves are happening in increasingly public spaces. Their intensification appears to be aimed at preventing a replay of the shock results of the 2013 general elections, when the ruling party lost 22 seats to the CNRP, giving the ruling party its lowest share of seats since 1998.

2013: the beginning of the end

I was in Cambodia for the 2013 elections doing research for my PhD on the legacy of the Khmer Rouge regime. My work involved examining contemporary Cambodian politics.

The success of the opposition took many of us by surprise. Despite the allegations of fraud and corruption, the result seemed promising for its indication of free voting – there was hope that it marked a positive move for democracy. But among threats of civil conflict and unrest, the result also provoked tension.

Protests occurred in the capital, and several people were shot. Rumours started to circulate that Hun Sen had mobilised the army and that the deputy prime minister, Sok An, was planning a coup. Fear and tension bubbled below the surface for many of the people I was working with.

Hun Sen has repeatedly threatened civil war should he lose the elections. His threats are grounded in the all-too-well-remembered violent history of the Khmer Rouge, when up to 1.7 million people were killed.

In 2011, following the Arab Spring, Hun Sen threatened to kill anyone resisting his rule. Earlier this year he said:

To ensure the lives of millions of people, we are willing to eliminate 100 or 200 people.

Some in Cambodia fear he will be true to his word. It seems unlikely that Hun Sen will let the 2018 election result get as close as it did in 2013. After all, he has never shunned the threat of violence as a means of control.

Hun Sen also has the support of Tep Vong, supreme patriarch of the Cambodian Buddhist sect of Mohanikay. He has previously condoned controlling the freedom of the people, thereby ensuring spiritual legitimacy as well as political impunity for Hun Sen’s actions.

Global shifts in despotism, crumbling democracies

The moves towards media control and suppression of the opposition parallel turns across the globe. They reflect the rolling back of democracy and a rise of autocratic leaders in so-called democratic countries.

In April this year, a referendum in Turkey voted for constitutional reforms that give President Recep Tayyip Erdoğan single-handed rule with the right to pass new laws and dissolve parliament at will.

This legislation followed the failed coup in 2016. In the subsequent crackdown thousands of journalists, academics and lawmakers were jailed, and at least 156 media outlets forced to close. Turkey now has more journalists in prison than any other nation.

Philippines President Rodrigo Duterte has admitted murder, threatened killings of drug dealers (and likened himself to Hitler in the process) and said he would pass political impunity laws to protect himself. More than 7,000 people have reportedly been killed in the last year.

In Poland, the ruling party passed legislation restricting the freedom of the press and giving itself increasing control of the courts. Only the prime minister’s signature is needed for action.

According to US think tank Freedom House, 2016 was:

… characterised by an erosion of democratic institutions and a rise of autocratic practices across the globe.

Political violence, open suppression

Violence in politics is not new. The control of the people in Cambodia is not new. What is new is the increasing confidence of leaders, such as Hun Sen, to flex their political muscles openly and violently with complete confidence in their political impunity.

Cambodia is often heralded as a nation with an exciting future due to high levels of investment and development support. But the success of its peace and democracy is openly crumbling.

The CPP needs a powerful opposition to prevent complete disintegration of democracy and human rights. It’s making sure that is not possible.
