At the same time, a growing volume of international commodities are coming into China by air.

同时，也会有越来越多国际货物通过空运国市场。

如果空运货物在机场延误了怎么办？

Before the ban, loads were flown in from Africa and distributed from warehouses near Heathrow airport—in 2013 around 15m-worth ($25m) was imported from Kenya.

禁令之前，货物从非洲空运，而且分布在伦敦希斯罗机场仓库货物—2013年价值1500万是从肯尼亚口。

You know, if a shipment's being delivered by air, it'll be a little faster, but certainly it'll take days or weeks for these tariffs to really fully come into effect.

你知道， 如果货物是通过空运交付，速度会快一些， 但这些关税真正完全生效肯定还需要几天甚至几周时间。
