Myanmar's president told Japanese business leaders Friday that his country is eager for their investment as it carries out key politicial and economic reforms, according to AP. After shying away from Myanmar during its decades as an international pariah, many Japanese businesses are now taking a hard look - and some are already taking the plunge. Visiting Tokyo for this weekend's summit between the leaders of Japan and five Mekong region nations - Thailand, Cambodia, Vietnam, Laos and Myanmar - President Thein Sein said Japanese investment and know-how was needed to help shrink the economic gap between these nations and other more developed economies in Southeast Asia. "We hope that Japan's famous and successful firms ... will support us in this endeavor," he told a luncheon organized by the Keidanren, Japan's biggest business lobby. Japanese companies have held back from investing in Myanmar in recent years because they didn't want to upset relations with the U.S. and the EU, which have imposed sanctions on the country. Another factor was the lack of transparency in laws governing business and foreign investment. There have been moves toward lifting of Western sanctions after Myanmar's nominally civilian government implement a series of political reforms and economic over the past year, including releasing prominent political prisoners and allowing democracy icon Aung San Suu Kyi to run as a candidate - and win - in recent parliamentary by-elections. Myanmar earlier this month unshackled its kyat currency from government controls with the introduction of a managed float for the exchange rate. Asian investors and international tourists have started to flock to the country in recent months, and a number of Japanese companies have started projects and expressed interest in doing business in the desperately poor country.
