New sanctions from the Trump administration are forcing European and Asian firms to choose between their US and Iranian business interests.

The EU has created a special purpose vehicle called Instex to circumvent the US sanctions, but sanctions lawyer Nigel Kushner of W Legal says that the Iranians are right to feel unhappy with the effectiveness of this workaround.

Manuela Saragosa speaks to one British businessman who has already given up on trading with Iran, or indeed recovering the proceeds from his past transactions that remain trapped in an Iranian bank account. She also asks BBC Persian correspondent Jiyar Gor how the latest round of American sanctions are affecting the lives of ordinary Iranian citizens.
