Thailand, China and Laos will sign a memorandum of cooperation on a new bridge for a railway across the Mekong River during Prime Minister Prayuth Chan-o-cha’s Beijing visit this week, a Thai foreign ministry official said Tuesday. The bridge would link Thailand’s northeastern Nong Khai province with the Laotian capital Vientiane, Thai officials told BenarNews, in what analysts believe will reinforce China’s ambitions to build a high-speed railway network in Southeast Asia, stretching through Malaysia and feeding into Singapore.
