Although H. Satish Rao, Director General, OED, headed the East Asia Department, and Ramesh B. Adhikari, Director of Operations Evaluation Division 1, worked for the Southeast Asia Department, they were not involved in preparing, implementing, or supervising Greater Mekong Subregion projects. Mr. Adhikari supervised the report up to peer review. John Weiss and Carmencita Balbosa were the consultants. To the knowledge of the management of OED, there were no conflicts of interest among the persons preparing, reviewing, or approving this report. EXECUTIVE SUMMARY Introduction The Greater Mekong Subregion (GMS) program, an activity-based subregional economic cooperation program, began in 1992 under the sponsorship of the Asian Development Bank (ADB). It covers six countries—Cambodia, Lao People’s Democratic Republic (Lao PDR), Myanmar, Thailand, Viet Nam, and Yunnan Province and Guangxi Zhuang Autonomous Region of the People’s Republic of China (PRC). ADB assumed the role of the GMS Secretariat as well as roles of a facilitator, financier, honest broker, and technical adviser. An independent evaluation study of the GMS program undertaken by the Operations Evaluation Department (OED) in 1999 found that overall progress in the first 7 years of operation had been satisfactory, but it raised concerns about the lack of focus of the GMS program and limitations on the availability of ADB resources for regional cooperation. Its lessons included, among others, the need to demonstrate “regional” impacts, the importance of providing linkages between the national and regional programs, and the necessity for ADB to have an exit strategy. Only about a third of the lessons have been adopted so far. Given the limited time lag between the establishment of the GMS program and the 1999 evaluation, it was not possible to draw inferences about the program’s impact. The initial 10 years of the GMS program were characterized more by sector-specific initiatives rather than a holistic vision. It was not until November 2001 that the countries adopted a 10-year GMS Strategic Framework (GMS-SF) covering 2002–2012. Meanwhile, ADB developed a regional cooperation strategy and program (RCSP) in 2004 to complement country strategies and programming for 2004–2008. The overarching objective of the RCSP is supporting pro-poor sustainable growth. The ADB-wide regional cooperation and integration strategy of 2006 aims explicitly to move away from a focus on standalone projects and programs toward a more strategic approach. At the request of the Southeast Asia Department, OED undertook a regional cooperation assistance program evaluation (RCAPE) of ADB’s support to the GMS program. It is the first RCAPE done by OED and will provide directional inputs toward the next RCSP for the GMS program. It evaluates ADB-cofinanced GMS operations during 1992–2007. It does not, however, evaluate the operations financed by other aid agencies or by GMS member countries, nor does it cover any GMS activities in Myanmar, where ADB has no operational activity. It uses the evaluation framework developed for country assistance program evaluations involving a combination of “top–down” and “bottom–up” perspectives. The counterfactual is reviewed in the assessment of ADB’s past value added. Study Findings Member countries have benefited from subregional cooperation in the GMS, although tangible progress in terms of significant regional economic impact has been slow. From its outset, the GMS program was designed as a relatively flexible, activity-based program as opposed to a rules-based form of cooperation. This means that member countries collaborate on specific activities involving limited cooperation and limited lending to key sectors—principally roads and power infrastructure, and to a lesser extent tourism. ADB has provided 40% of the funds (about $3.5 billion for GMS loans and special grants and about $82 million for GMS technical assistance [TA]) for the ADB-sponsored GMS program, while another 35% has come from member countries and 25% more from other development partners. ii The negative comments on some aspects of the GMS should not detract from the overall judgment that progress, while slow, has been positive. Despite problems in individual sectors and projects, ADB has played an important catalytic role,
