DOHA, June 28 (Reuters) - Qatar Petroleum QATPE.UL will cede control of parts of the industrial city of Mesaieed in 2017 as the state-owned corporation restructures to focus on its core business at a time of low oil prices and increased competition in energy markets.

Control of 200 projects in Mesaieed, a centre for petrochemical and oil refining activities 40 km (25 miles) south of Doha, will be transferred to Manateq, a state-owned company that manages Qatar's special economic zones in January.

The ceding of a light industries area, concrete plant and raw materials storage area to Manateq will allow QP to focus on its "core business activity," QP's CEO Saad al-Kaabi said in a statement.

QP said on Sunday it would absorb Qatar's petroleum products marketing company, Tasweeq, by the end of the year to save costs for QP in a demanding market environment. urn:newsml:reuters.com:*:nL8N19I07O
