State Food and Drug Administration
China's thousands of domestic companies account for 70% of the market, the top 10 companies about 20%, according to Business China. In contrast, the top 10 companies in most developed countries control about half the market. Since June 30, 2004, the State Food and Drug Administration (SFDA) has been closing down manufacturers that do not meet the new GMP standards. Foreign players account for 10% to 20% of overall sales, depending on the types of medicines and ventures included in the count. However, sales at the top-tier Chinese companies are growing faster than at Western ones.
