China has overtaken the U.S. as the world’s largest importer of crude oil for the first time, according to a report from the Financial Times (FT) on Sunday.

Highlighting a seismic shift in global energy flows over the past decade, China has eclipsed the U.S. in April and has became the top global crude importer.

According to the FT, Chinese customs statistics for April showed that crude oil purchases from overseas had hit a new high of 7.4 million barrels per day, accounting for around 1 in every 13 barrels consumed worldwide and and topping U.S. imports of 7.2 million barrels per day.

The report said that although China’s imports are not expected to consistently surpass those of the U.S. until the second half of this year, the data highlights how the U.S. shale revolution has reduced the nation’s reliance on foreign oil — and how China’s demand continues to grow, even as its economy slows.
