AT least 15 Asian countries, including communist North Korea, participated in Cambodia’s fourth Import-Export and One Province, One Product Exhibition on Tuesday in Phnom Penh. However, the impact of the global economic crisis meant just 126 companies joined the four-day expo – held at the capital’s Mondial Centre – compared with 201 firms last year, both domestic and from overseas. Commerce Minister Cham Prasidh noted that Japan had the largest presence, taking up 10 booths at the exhibition out of 96 run by foreign enterprises hoping to sell their products in Cambodia.
