PHNOM PENH -- A lack of transparency threatens to undermine Vietnam's rubber industry, experts and industry figures say, as global buyers increasingly demand material that meets stringent ethical and legal standards.
Vietnam ranks fifth in the world for land for rubber cultivation -- some 926,000 hectares in 2020 -- but is third globally for output, producing some 1.22 million tons in 2020, according to a report last year by Forest Trends.
