DOHAinfo-icon:- Qatarinfo-icon is to leave OPECinfo-icon next month in order for the Gulf state to focus on gas production, the country's new Energy Minister Saad al-Kaabiannounced in a surprise move on Monday.

Qatar has been a member of OPEC since 1961, and the decision to pull out comes at a turbulent time in Gulf politics, with Doha under an 18-month-long boycott by former allies including Saudi Arabiainfo-icon.

"Qatar has decided to withdraw its membership from OPEC effective January 2019 and this decision was communicated to OPEC this morning," Kaabi said at a Doha press conference. 

Kaabi, who also heads state-owned Qatar Petroleum, denied the move was linked to the feud with the Saudi Arabia-led bloc.

The decision was "technical and strategic" and had "nothing to do with the blockade," he said.

Qatar would continue to produce oilinfo-icon and seek deals in countries including Latin Americainfo-icon's top oil producer Brazilinfo-icon, said Kaabi. 

But gas production would remain the top priority for Qatar, which is the worldinfo-icon's the biggest exporter of liquified natural gas (LNG).

"We don't have great potential (in oil), we are very realistic," said Kaabi, who described himself as "Mr Gas" during the conference. "Our potential is gas."

"I think it's inefficient to focus on something that's not your core businessinfo-icon and something that's not going to benefit you long-term."

In September Qatar announced it planned to boost gas production to 110 million tonnes per year by 2024.

Qatar's oil production is around 600,000 barrels per day and it is the world's 17th largest producer of crude oil, according to specialist website, worlddata.info.

It also only holds around two percent of the world's global oil reserves, according to the CIA World Factbook.

Kaabi said OPEC had been informed of the decision on Monday ahead of the announcement and that he would still attend the organisation's Vienna meeting later this week, his "first and last" as energy minister.

That meeting is expected to set a policy for 2019 and despite Qatar's announcement, oil prices soared on Monday after Russiainfo-icon and Saudi Arabia renewed a pact to cap output. By walking away from OPEC's production restrictions, Qatar could increase output and undermine efforts to control prices.

OPEC is dominated by oil-rich Saudi Arabia, which along with its allies has had no ties with Qatar since June 2017.

Relations between Riyadh and Doha are at an all-time low as a result of the crisis, which has seen Saudi-led countries accuse Qatar of supporting terrorism and being too close to Iraninfo-icon.

Qatar refutes the allegations and claims rivals want to overthrow its government.
