Abstract: In the Washington Conference, Britain's request about conditionally increasing China's tariff was conditionally satisfied. The Peking Government's appeal for increasing China's tariff so as to get rid of financial crisis was un successful,only getting the promise of agreeing to the effective rate of 5 percent, surtax 2.5 percent and surtax not more than 5 percent of luxury goods which was a success compared to that of agreeing to the effective rate of 3.7 percent before. The Special Commission made by the nine powers controlled the surtax 2.5 percent which couldn't be used freely by the Peking Government. But the powers, including Britain, couldn't take the chance of revising the tariff to control China's finance.
