THE government Monday signed a memorandum of understanding with the Japan External Trade Organisation (JETRO) aimed at boosting trade, investment and industrial development. JETRO will establish an office in Phnom Penh in March, according to a copy of the agreement. Official figures showed that Japan invested just US$148 million in Cambodia between the end of 1994 and the end of the third quarter this year, compared with China’s $6.511 billion and $2.856 billion by South Korea over the same period.
