世界急切需要一个有效的世贸组织。

The world desperately needs an effective WTO.

毕竟他们在2005年做成了13万亿的国际贸易，而世贸组织是这个成就的基石。

They were, after all, responsible for about $13 trillion of trade in 2005, and the WTO underpins this success.

然而，在那期间，世贸组织成员没有调整他们可以维持的商品和服务的最高关税水平和其他壁垒。

During that time, however, WTO members have not adjusted the maximum levels of tariffs and other barriers that they can maintain on goods and services.
