COMMERCE Minister Cham Prasidh told a meeting of the five least-developed World Trade Organisation (WTO) members Wednesday that easing trade flows was critical to recovering from the global economic crisis. “Cleaning our house and building the best enabling environment for our traders, manufacturers and investors will be conducive to sharpening our competitive edge,” he told officials from Afghanistan, Bangladesh, Bhutan and Laos at a two-day workshop on trade facilitation that shared experiences on the Doha round.
