Iranian exports to China, South Korea, India, and Japan climbed 20% in September, compared to August, to reach 1.9 million barrels per day (b/d), Reuters reports.

The figure represents a 5.1% year-on-year (y.o.y.) increase from September 2016, according to the news agency.

Exports to Japan and India fell, but were more than offset by rising demand from China and South Korea.

Crude exports to China, while lower than in August, rose almost 60% y.o.y to hit 784,000 b/d. Following China, South Korea imported 504,000 b/d, India 415,400 b/d, and Japan approximately 216,000 b/d, according to Reuters. 

Iran’s total exports in September were 2.28 million b/d, according to data compiled by Bloomberg.
