The Gulf Cooperation Council (GCC) signed a free trade agreement with South Korea on Thursday, its second trade deal this year, as the six-member bloc intensifies efforts to boost investment ties with major economic partners in Asia.

South Korea will remove tariffs on almost 90% of all items, including liquefied natural gas (LNG), and other petroleum products, according to South Korea's Yonhap news agency, while the Gulf states will scrap tariffs on 76.4% of traded products and 4% of traded goods.

The FTA will also cover trade in goods, services, government procurement, as well as cooperation among small and medium-sized enterprises (SMEs), customs procedures, intellectual property, among others, a GCC statement said.

The GCC has signed few FTAs due to the complications of navigating competing priorities within the bloc, and talks such as those with China, which began in 2004, can take years.

Trade talks have, however, gathered momentum as Gulf states - largely dependent on oil and gas for revenue - seek to diversify their economies and develop new sources of income.

Trade between the Gulf and South Korea jumped to $78 billion from $50 billion between 2021 and 2022, according to data from London-based think tank Asia House, while the bloc's trade with emerging Asia, which includes China, surged to $516 billion last year from $383 billion in 2021.
