The Japanese government has approved a 63 billion yen (about 24 billion baht) loan to the Thai government to fund an extension of a BTS skytrain line. The loan will finance the construction of the red line, which will start in Rangsit in Pathum Thani province and pass through Bang Seu and Hua Lumpong in Bangkok to Mahachai in Samut Sakhon province. The Thai Prime Minister is on a three-day official visit to Japan to boost Japanese investors' confidence in the Thai economy and to strengthen trade ties between the two countries. The Japanese premier has expressed his wish to see countries in ASEAN work together through the global economic downturn.
