In a major U-turn, Turkey has agreed to solely deal with the central Iraqi government over crude oil exports, following a contentious secession referendum held by Iraq’s semi-autonomous Kurdistan region, the Baghdad government says.

According to Press TV, the office of the Iraqi Prime Minister Haider al-Abadi reported Ankara’s change of mode on Thursday, following a phone call between Abadi and his Turkish counterpart, Binali Yildirim.

Yildirim “confirmed the support of his country on all decisions” taken by the Iraqi government, said the statement.

As part of the measures, Turkey would restrict oil export operations to the Baghdad government, it added.

The Turkish PM also emphasized Ankara’s “commitment to cooperate and coordinate fully with the Iraqi government to implement all necessary steps for imposing of federal authorities at land and air ports,” according to the statement.

Ankara has long been buying oil from the Kurdistan Regional Government (KRG) in defiance of Baghdad’s stiff opposition.

Oil exports serve as the KRG’s main source of income. The Kurdistan region exports an estimated 650,000 barrels of oil per day through Turkey’s Ceyhan pipeline.

Turkish government spokesman Bekir Bozdag also said Thursday that Ankara is set to conduct its dealings in Iraq with the central government, and that the two premiers will sit down down for talks soon.
