trade credits

The availability of credits lubricated the channels of trade.

信用证的使用使贸易渠道更为畅通.

Over the past decade Beijing has disbursed more than$ 100bn of trade credits and investment to the region and this week some of its biggest clients are coming cap in hand, seeking fresh funds to tide them through lean times.

过去10年里，北京向该地区输送了超过1000亿美元的贸易信贷和投资。本周，中国一些最大的附庸国却登门讨钱，寻求获得更多资金帮助他们度过不景气时期。

That could be a carbon tax or a cap-and-trade system, such as Europe's Emissions-Trading Scheme, which limits how much producers can emit, and lets them buy and sell emissions credits.

可以考虑提出一套碳税体系或一套限额交易体系，例如欧洲的排放交易方案（ETS），该方案对生产商的碳排量作出了限制，并允许他们买卖排放信用（emissions credits）。

Trade credits are drying up too.

伊朗的贸易信用也正逐渐殆尽.
