Another question is whether Europe does eventually ban piped Russian oil, which is harder to redirect to other countries.

另一个问题是，欧洲最终是否会禁止通过管道输送俄罗斯石油，因为这些石油更难转向至其他国家。

Oil production was halted early last year after landlocked South Sudan accused its neighbour of hiking transit fees to pipe the oil to international markets via Port Sudan.

去年年初，内陆国家南苏丹指责苏丹向通过苏丹港送往国际市场的石油收取过高的过路费。

However, the ban will not cover piped oil, an exemption sought by the Czech Republic, Hungary and Slovakia, which rely heavily on pipeline supplies, and it will be phased in.

然而，这项禁令并不包括管道石油，这是捷克共和国、匈牙利和斯洛伐克寻求的一项豁免，这些国家严重依赖管道供应。这项禁令将逐步实施。
