Prime Minister Yingluck Shinawatra led a delegation to visit Japan on 22-25 May 2013, and took the opportunity to explain to the audience Thailand's major investment plans and how both countries would benefit. She said that Japan is now the largest group of foreign investors in Thailand. Apart from the automotive industry, Thailand invites Japanese business people to invest more in energy development and agricultural processing in Thailand. The Prime Minister pointed out that Japan invested in the Laem Chabang deep-sea port on Thailand's Eastern Seaboard 20 years ago and that it should place additional investment in the planned Dawei deep-sea port in Myanmar, as well. The Dawei deep-sea port will link with Laem Chabang and will also offer great business opportunities.
