“A ‘renminbi bloc’ has been formed in East Asia, as nations in the region abandon the US dollar and peg their currency to the Chinese yuan — a major signal of China’s successful bid to internationalize its currency, a research report has said. Now seven out of 10 economies in the region — including South Korea, Indonesia, Malaysia, Singapore and Thailand — track the renminbi more closely than they do the US dollar. Only three economies in the group — Hong Kong, Vietnam, and Mongolia — still have currencies following the dollar more closely than the renminbi, said the report.”
