Iranian exports to its major Asian customers were down 29% year-on-year in November, Reuters reports.

Exports to China, Japan, India, and South Korea were at 1.36 million barrels per day (b/d), the news agency reports. The totals reflect Iran’s lowest volume of shipments to the importers since April 2016.

In September, Iran exported 1.9 million b/d to the four major Asian buyers, Reuters previously reported.
