PRIME Minister Hun Sen said Thursday he planned to incorporate Kratie province into the Emerald Triangle Cooperation Framework, a tourism, infrastructure and trade promotion zone linking northeastern Thailand, northwestern Cambodia and southern Laos. Ratanakkiri, Mondulkiri and Stung Treng provinces are already part of the economic zone. He was speaking at a groundbreaking ceremony for a new section of National Road 78, which is being built between O’Pong Moan and Banlung Town in Ratanakkiri province with a $73 million concessional loan from China.
