So trying to parse this out as a non-economist:<p>- first order effect: Yuan gets cheaper, meaning non-Chinese can buy more Yuan per dollar or unit of their currency<p>- second order effect: non-Chinese can buy more units of Chinese goods, making Chinese exports more competitive.<p>- second order effect: Chinese can buy less non-chinese goods per Yuan, weakening the ability of China to import items, but potentially strengthening the domestic market.<p>I imagine this will also create some amount of inflation.<p>An interesting technicality is that Chinese currency trades in two separate, mainly correlated markets. The onshore market (CNY) is regulated in a very tight band by the central bank, the offshore market (CNH) is much less controlled and trades in Hong Kong.<p>See <a href="https://www.google.com/search?q=cny+vs+cnh" rel="nofollow">https://www.google.com/search?q=cny+vs+cnh</a> for the linkage.
