Nine EU nations and Japan have been exempted from American financial sanctions after having reduced oil purchases from Iran, but China and India are still exposed to the threat of restrictions, says Reuters. China and India are Iran's two largest buyers of oil, and those two, plus Japan, purchase close to half of Iran's crude exports.

The sanctions are designed to pressure Iran into shutting down its nuclear program by cutting the country's sources of financing. This has made it difficult for them to transfer funds to pay for trade, and has also forced them to readjust oil shipments due to difficulty in securing shipping insurance. Iran's currency, the rial, has also fallen in value. Nations that refuse to reduce their reliance on Iranian oil expose themselves to the threat of the sanctions.

Japan has been a model for cutting oil reliance on Iran after its 15%-22% reduction estimation, even after the earthquake and nuclear power plant disaster. Carlos Pascual, Special Envoy and Coordinator for International Energy Affairs at the State Department, said, "If Japan was able to do what it did ... that should be an example to others that they could potentially do more."
