Saudi Arabia cuts crude oil exports to iJapan, South Korea and China, its three largest Asian customers by nearly 4 percent in the fourth quarter against the third.
The Saudi cuts of a total 88,000 barrels per day (bpd) support other evidence showing compliance with OPEC curbs that came into force on November 1.
Japan, South Korea and China together imported some 2.362 million bpd of Saudi crude during last quarter, or about a third of the kingdom's total exports.
That was down a hefty 5.4 percent, or 135,000 bpd, from a year ago.
OPEC agreed to lower its supplies by 1.2 million bpd from November 1 in an attempt to shore up prices, with top exporter Saudi Arabia expected to bear the brunt with a 380,000-bpd reduction.
