The European Commission has proposed changes to its plan to embargo Russian oil, in a bid to win over reluctant states, an EU source told Reuters on Friday.

The tweaked proposal, to be discussed by EU envoys at a meeting on Friday starting from 0730 GMT, would include a three-month transition before the introduction of a ban on shipping services to transport Russian oil, instead of the initial one month. It would also entail help with investments to upgrade oil infrastructure and mitigate the impact of the sanctions.
