Currency War-US, Europe are unjust in their demand for YuanappreciationThe rate of exchange between US$ and Chinese Yuan is around $1= Yuan 6.7. US(and other developed countries in Europe etc) thinks that Yuan is undervalued to the extent of about 25% i.e. their view is that the rate should be around $1= Yuan 5 or 5.5. The arguments of US is that since the Yuan is undervalued, products imported from China into US are cheap compared to local products, and this is detrimental to the US industry, and leads to job cuts estimated at around 0.5 million. Further, US products exported to China are expensive in China and hence US exports suffer. Chinas foreign exchange reserves are very large (around $2650 billion) and this should normally make Chinas local currency appreciate against other currencies but it is not happening. . According to US, China manipulates the exchange rateUS argument is not fully justified because,i).it does not take into account, the fact the China exports to around 200 countries and the number of countries affected by current rate of exchange are only a few. Most of the developing countries benefit when prices of imported products are low.ii) Many countries do not have the concerned industry and the question of the local industry suffering or workers losing jobs do not arise at all.iii) Where local industry exists, Chinese equipments and products fill the gap between supply and demand, at comparatively low prices thus meeting requirements of importing country and helping industrialization of that country.iv) Even in US, the general public will only be happy to get their requirements from China at a lower rate. The large number of consumers is not bothered about the job loss for a few hundred thousand people or manufacturers suffering loss.v)To protect the local industry and save the jobs, US could think of means like imposing/increasing import duties on Chinese products, assisting the exporters with incentives like low interest rate for exporters, exemption from tax for profits from exports etc.vi) US could think of means of making its industry competitive in relations to Chinese industry, by asking workers to increase their productivity, upgrading technology, minimizing overhead expenses etc..vi) US(also European) industry being affected by Chinese exports or its inability to export to China is a bilateral issue and should not be made a multilateral issue as the US gain from appreciation of Yuan will harm many, particularly developing countries importing from China.
