BANGKOK >> Police in Thailand shut down a forum organized by foreign journalists to discuss whether senior military officers in Myanmar should face justice for alleged human rights abuses committed by their forces against Rohingya Muslims and other ethnic minorities.

About a dozen policemen showed up ahead of today’s scheduled panel discussion at the Foreign Correspondents Club of Thailand and ordered the panelists not to speak. The scheduled speakers included Tun Khin, a prominent U.K.-based Rohingya activist; Kobsak Chutikul, a former Thai diplomat; and Kingsley Abbott, a representative of the International Commission of Jurists, a rights advocacy group.

Last month a specially appointed U.N. human rights team recommended that Myanmar military leaders should be prosecuted for genocide against the Rohingya. Critics of Myanmar’s military have also accused it of carrying out ethnic cleansing and other war crimes.

Some 700,000 Rohingya fled across the border to Bangladesh after the army launched a counterinsurgency campaign in response to attacks by Rohingya militants last August.

Myanmar’s army, which for decades has been accused of violating the human rights of various ethnic minorities, denies having committed organized rights abuses.

The police at the Bangkok event handed over a letter requesting the panel discussion on “Will Myanmar’s Generals Ever Face Justice for International Crimes?” be canceled because it could damage national security, affect foreign relations and a give a third party the opportunity to create unrest.

However, Police Col. Thawatkiat Jindakuansanong told the organizers: “We are not asking. We are ordering you to cancel the event.”

Dominic Faulder, the president of the Foreign Correspondents Club, expressed his disappointment and said he had no choice but to announce the cancellation.

It is believed to be the sixth time police have forced a cancellation of one of the group’s programs since Thailand’s military seized power from an elected government in 2014. Politically sensitive events in other venues have also been stopped.

Scheduled panelist Abbott, a senior international legal adviser with the International Commission of Jurists, chided Thai authorities for the shutdown.

“This is an issue of global concern and Thailand, as Myanmar’s neighbor and a leading voice in ASEAN, should be taking a leadership role in addressing the situation,” he said. ASEAN is the Association of Southeast Asian Nations, a 10-member regional grouping.

“Thailand’s decision to order the event not to proceed is enormously disappointing and represents a lost opportunity to discuss the situation and identify possibilities for accountability in an open forum in the region,” he said.
