US Secretary of State Hillary Clinton has raised pressure on India to reduce further its imports of Iranian oil.
Visiting the country where she met Prime Minister Manmohan Singh, Clinton said Washington was encouraged by steps taken but more was needed.
As Tehran’s second-biggest crude customer, India is crucial to US efforts to squeeze Iran’s economy until it agrees to curb its nuclear programme.
“We do not believe Iran would have come to the table had there not been sanctions and pressure. We do not believe Iran will peacefully resolve this unless the pressure continues,” Clinton said.
India could face US financial sanctions if it fails to make cuts deemed adequate.
The US and other Western nations suspect Iran’s nuclear activity is aimed at building atomic weapons, something Tehran denies.
