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

同时，也会有越来越多的国际过空运进入中国市场。

What happens if the air freight gets held up in the airport?

如果空运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，从非洲空运，而且分布在伦敦希斯罗机场附近的仓库的—2013价值1500万是从肯尼亚进口的。

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， 如果是过空运交付的，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的时间。
