Southeast Asian leaders will seal a tourism pact at their summit in Cambodia next month to revive confidence in the region following the bloody bomb blasts in Bali, Tourism Minister Abdul Kadir Sheikh Fadzir said today.

The decision to deepen tourism cooperation among the 10-member Association of Southeast Asian Nations (Asean) was made two years ago but there was more urgency now following the Bali tragedy, said Abdul Kadir.

"The leaders will sign an Asean tourism agreement in Cambodia. It will spell out the decision of all Asean countries to work together to promote tourism to the region and also intra-Asean travel," he told reporters.

"We want to help each other in tourism, to encourage intra-Asean travel. Maybe the richer Asean countries will invest in hotel resort development in the not-so-rich ones. It's cooperation in the wider sense."

The annual Asean summit on Nov 4-5 in Phnom Penh will bring together leaders from Burma, Cambodia, Laos, Vietnam, Singapore, Brunei, Indonesia, Malaysia, the Philippines and Thailand.

Heads of state or high-ranking officials are also expected from China, Japan, South Korea and India.
