Iranian oil exports hit a high in December, just one month after Western nations inked a nuclear pact with Iran that guaranteed up to $7 billion in economic sanctions relief.

Exports of Iranian crude oil rose from 789,292 barrels per day in November to 1,059,605 per day in December, according to new shipping data provided to the Washington Free Beacon by the advocacy group United Against Nuclear Iran (UANI).

This is among the highest number of oil exports Iran reached in all of 2013. Iran hit its peak oil sales in April of that year, when it was exporting some 1.39 million barrels per day.

Some foreign policy experts worry that the interim nuclear deal reached between Iran and the West has reinvigorated the global markets and created a renewed demand for Tehran’s cheap—and heavily sanctioned—crude oil.

China, India, South Korea, Turkey, and Syria are currently the top five importers of Iranian oil, according to UANI’s shipping data.
