The 16 nations that use the euro are urging China to let the value of its currency rise to help stimulate global economic growth. Jean-Claude Juncker of Luxembourg, the head of the 16 EU nations that use the euro, wants to see a 'broad-based appreciation' of the Chinese yuan against the dollar and other major currencies. He said he expressed the view at a meeting Tuesday with Chinese Prime Minister Wen Jiabao. Also at the meeting were EU Monetary Affairs Commissioner Olli Rehn and European Central Bank President Jean-Claude Trichet. Juncker told reporters China's 'effective exchange rate remains undervalued.' He says the EU wants China to stoke more domestic demand and added the euro-yuan exchange rate is not 'what we would have hoped.'
