DOHA, Oct 31 (Reuters) - Qatar Petroleum QATPE.UL established a global liquified natural gas (LNG) marketing arm on Monday to manage its future LNG supply portfolio.

Ocean LNG is a joint venture owned by affiliates of QP and ExxonMobil XOM.N , with 70 percent and 30 percent stakes respectively, and aims to "pursue market development opportunities in emerging and new markets", QP Chief Executive Saad al-Kaabi said in a statement.

An Ocean LNG branch office will be established in the Qatar Financial Centre in Doha, the statement said.

In June QP said it would absorb Qatar International Petroleum Marketing Co, known as Tasweeq, to maximize value for QP in an increasingly competitive and demanding market. urn:newsml:reuters.com:*:nL8N19I07O

Qatar is cutting costs at state-owned enterprises to contend with low oil and gas prices.

The Gulf country faces increased competition in energy markets from other LNG producers as new projects in the United States and Australia come online in the next few years.
