Critics say China's currency is undervalued by 20%. China is only willing to increase the value of the yuan by 3% this year, fearing that a signifcant revaluation will lead to the closure of textile and other factories in the coastal areas that operate on a small profit. Facing high unemployment the US is not willing to let this happen gradually. US businesses that manufacture in the US and export to China would benefit if the yuan appreciates significantly. Retailers such as Wal-Mart and textile producers with offshore manufacturing at contract sites in China are on the other side as they benefit from the lower value of the Chinese currency.
