Thousands of Cambodian armed forces were on training Wednesday aiming at providing security and safety for the 20th ASEAN summit and related meetings from March 30 to April 4.

The training was held at the capital's Diamond Island Center with the participants from police, soldiers, riot police, military police, anti-terrorism police, fire police, traffic police, and guards of honor as well as protocol officials.

Speaking to reporters during the training session, Lieutenant General Chuon Sovan, deputy chief of the National Police, said that during the upcoming summit, the security forces would mainly focus on anti-terrorism.

"Security will be tightened at the airport, meeting venues, delegate buses, hotels, and roads in order to prevent any terrorism plot," he said, adding "we also train our forces to prevent any protest during the summit."

Brigadier General Touch Narath, Phnom Penh police chief, said that security and public order in the city have been beefed up from now on through routinely patrolling and searching for weapons and explosions at night among passengers.

"Also, security and safety at hotels and guesthouses have been strengthened, and street businesses along main roads will not be allowed until the end of the summit," he said.

The 20th ASEAN summit and related meetings will be held at the capital's Peace Palace.
