West considers early sanctions moves in troubled Iran nuclear talks

BRUSSELS/VIENNA (Reuters) - With talks between world powers and Iran over a broad nuclear accord at an impasse, Western governments are considering offering a significant easing of sanctions early on in the process to try to wring concessions from Tehran, diplomats say.

To be effective, such a plan would have to involve clear guidance to companies made wary by U.S. fines for sanctions-busting, be reversible and not go too far, or sceptical U.S. lawmakers would simply reimpose restrictions.
