Nearly a fifth of all products sold in China fail to meet the country's quality standards, regulators have admitted, the Wall Street Journal reported. In the first half of 2007, the General Administration of Quality Supervision, Inspection and Quarantine reviewed 114 types of product made by more than 6,300 companies and found that 19.1% of them were substandard. Larger companies proved more reliable, with 93.1% of their goods meeting requirements. Bottled water, canned fruit, dried fish, linens and grass-cutting equipment were among the product categories singled out as persistent offenders. However, improvements were noted in the quality of beer, fruit and vegetable drinks, electric fans and wooden floorboards. The regulator's report comes in the wake of widespread concern at the quality of goods exported by China, with numerous products being recalled in the US and elsewhere. Problems have arisen in products ranging from pet food and seafood to toys and toothpaste.
