The Bangkok bomb blast will affect tourism industry in Cambodia because Thailand is a main gateway of international tourists to the country, Tourism Minister Thong Khon said Wednesday. "Generally, there are some spillover effects on our tourism industry because about 40 percent of the international tourists enter Cambodia through Thailand,"he told reporters."We hope that the situation in Bangkok will return to normalcy soon."

According to the minister, after the Bangkok bomb blast, security has been tightened in Cambodia, especially at tourist destinations.

Tourism is one of the four pillars supporting the economy in Cambodia. Data revealed that Cambodia received about 2.3 million foreign visitors in the first six months of 2015, up 5.6 percent compared with the same period last year.

A bomb exploded at Erawan Shrine, a popular tourist destination in downtown Bangkok, Monday night, leaving at least 20 people dead and more than 100 others injured, according to the Thai National Police.
