Turkish President Tayyip Erdogan voiced his support for the Iraqi government’s plan to reopen the Kirkuk-Ceyhan pipeline, Reuters reports.

The pipeline was closed in 2014 as the Islamic State militants swept across northern Iraq, according to AP.

Earlier this month the Iraqi government announced plans to reopen the pipeline to Turkey, the Financial Times reported at the time.

The timeline for pumping oil through the pipeline is uncertain after several years of idleness, according to the Financial Times.

The reopening of the pipeline would permit Iraqi exports to largely bypass the Kurdistan Regional Government (KRG). Tensions between the two have been on the increase. Last week the central government initiated a military campaign to seize Kirkuk and its valuable oil fields from forces loyal to the regional government.

As Kurdish forces withdrew from Kirkuk, production from its oilfields dropped, resulting in lower crude exports through the KRG’s pipeline to Turkey.

Kurdish and Kirkuk crude oil transiting the pipeline is no longer blended, Reuters reports. Instead KRG and Kirkuk oil are pumped separately.
