A thing to remember in this are the sizes of the various markets.<p>NYSE, the largest in USA, has a combined market value of 20 trillion dollars, whereas the largest in China (Shanghai Stock Exchange) has a combined market value of 4 trillion. This is for two economies of about the same size.<p>This means that when the Chinese market drops (or raises) the overall impact for the wealth of the country is much smaller than a similar change would cause in the American markets.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Stock_exchange" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Stock_exchange</a>
