PHNOM PENH, March 21 -- Cambodian Prime Minister Hun Sen said Friday that the country is still conducting search operations for the missing Malaysian Airlines flight MH370 within its territory although Australia's satellite had sighted suspicious debris of the missing jet in the southern Indian Ocean.

"Even though Australia has sighted suspicious objects in the Indian Ocean, we have not abandoned our search operations in Cambodia. Our search is still going on," the prime minister said during the closing ceremony of the annual conference of the Education Ministry.

He also ordered to local authorities in all provinces to search in any suspicious areas.

Hun Sen said Cambodia will welcome Chinese and Malaysian experts if they are willing to come to Cambodia for further search operations.

Meanwhile, the prime minister expressed his deep sympathy to the relatives of the passengers onboard the missing jetliner.

"We wish that the search and rescue teams from our friendly countries would find the missing plane soon so as to end the anxiety of the family members of the passengers," he said. "Until this hour, the chance of survival is gone, except the plane was hijacked to any place, but such thing could not happen."

On Tuesday, the Cambodian Ministry of Defense sent four Z-9 utility helicopters and two naval vessels to conduct search operations for the missing jet at sea and on land within the country's territory.

The flight MH 370, carrying 239 people including 154 Chinese nationals en route from Kuala Lumpur to Beijing, mysteriously disappeared from radar in the early hours of March 8 over south Vietnam.

Malaysia's acting Transport Minister Hishammuddin Hussein said earlier this week that the number of countries involved in the search and rescue operations had risen to 26.
