The controversy surrounding missing Malaysia Airlines Flight MH370 has prompted many Chinese tourists, who once saw Malaysia as an attractive holiday destination, to look elsewhere, travel agents said on Tuesday.

Eleven Chinese travel agents told Reuters that bookings between China and Malaysia had fallen severely, and that many people have cancelled their trips, amid anger at the perceived lack of information provided by the Malaysian government to passengers' families.

"We used to have 30 to 40 customers a month for group tours to Singapore, Malaysia, and Thailand. Now there is no one asking about this route or booking," a travel agent surnamed Chen told Reuters by telephone.

"Tourists don't even consider going there. Many also have a negative impression of the country now," said Chen with Comfort Travel, in the southern city of Guangzhou, which focuses heavily on Southeast Asia tours.

In Beijing, angry relatives of Chinese passengers aboard the missing plane protested on Tuesday outside the Malaysian Embassy, demanding an explanation from the airline and accusing the government in Kuala Lumpur of "delays and deception".
