The Thai Canal, also known as Kra Canal or Kra Isthmus Canal, refers to proposals for a canal that would connect the Gulf of Thailand with the Andaman Sea across southern Thailand. It is envisaged that such a canal would improve transportation in the region, similar to the Panama Canal and Suez Canal. The canal would provide an alternative to transit through the Straits of Malacca and shorten transit for shipments of oil to Japan and China by 1,200 km. China refers to it as part of its 21st century maritime Silk Road. Proposals for the canal in 2015 measure 102 km long, 400 meters wide and 25 meters deep. Plans for a canal have been discussed and explored at various times, but have not been implemented. Cost and environmental concerns have been weighed against the potential economic and strategic benefits. ==History== A canal through the Kra Isthmus, which would shorten shipping times around Asia, was suggested as early as 1677. Thai King Narai asked the French engineer de Lamar to survey the possibility of building a waterway to connect Songkhla with Marid (now Myanmar), but the idea was discarded as impractical with the technology of that time. In 1793, the idea resurfaced; the younger brother of King Chakri (Rama I) suggested it would make it easier to protect the west coast with military ships. In the early 19th century, the British East India Company became interested in a canal. After Burma became a British colony in 1863, an exploration was undertaken with Victoria Point (Kawthaung) opposite the Kra estuary as its southernmost point, again with negative result. In 1882, the constructor of the Suez canal, Ferdinand de Lesseps, visited the area, but the Thai king did not allow him to investigate in detail. In 1897, Thailand and the British empire agreed not to build a canal so that the regional dominance of the harbour of Singapore would be maintained. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Thai Canal」の詳細全文を読む スポンサード リンク
