“It also shows that China highly recognises the financial regulations, investment environment, and geographical advantages of Saudi Arabia,” Chen said, as he attended the opening ceremony with Bank of China president Liu Jin.

Saudi Central Bank governor Ayman al-Sayari and Saudi Arabia’s deputy investment minister, Saleh Ali Khabti, also attended the opening ceremony along with 250 guests, according to a BOC statement.

The Saudi-listed ACWA Power, Saudi Arabia’s Ministry of Investment, Ajlan & Bros Holding Group and Zhejiang Rongsheng Holding Group signed memorandums of understanding involving “internationalising” the yuan and green financing with BOC during the opening ceremony, the statement added.

The move came as part of a growing series of economic activities between China and Saudi Arabia, with their bilateral relations described as being at the “best stage ever” following President Xi Jinping’s state visit in December, with both countries facing souring relations with the West.

During the trip at the end of last year, Xi pledged to work towards widening the use of yuan in oil and gas trade in the region, amid a push to establish the currency internationally and weaken the US dollar’s grip on world trade.

Saudi Arabia is China’s largest source of crude oil imports, with 87.5 million metric tonnes (641 million barrels) shipped in 2022.

Amid efforts by state banks to tap potential in the Middle East, BOC’s new branch has been licensed to provide basic commercial banking services to individual consumers and small- to medium-sized businesses, ranging from deposit accounts and loans to mortgages and yuan transactions.

At the weekend, BOC president Liu also met Khaled Mohamed Salem Balama Al Tameemi, the governor of the central bank of the United Arab Emirates, to court more support for its yuan clearing in the region and potential cooperation with the nation’s sovereign wealth funds.

In an interview with local media in June, BOC said the new branch aimed to offer the yuan to the wider Middle East region to assist commercial and financial trade between China, Saudi Arabia and beyond.

“As there are many Chinese companies entering the market in the region, being able to trade and make financial transactions using [the yuan] would encourage Chinese companies to invest in the area,” an unnamed BOC spokesman responsible for the project was quoted as having said.

The Saudi Arabian government first agreed to allow BOC to open its branch in January 2020. At the time, Saudi Arabia had only 14 foreign banks, including ICBC.

BOC also has existing branches in Abu Dhabi and Dubai in the UAE, as well as Bahrain, Turkey and Qatar.

Li Tong, president of the bank’s investment banking unit, Bank of China International, said in June during the Arab-China Business Conference in Riyadh that the new branch in Riyadh would “push for financial cooperation, and further boost economic cooperation” between the two countries.

The bank has also been in discussion with local counterparts to offer panda bonds – yuan-denominated bonds sold by overseas entities in China’s onshore bond market to raise investments in China.

A number of other banking sector collaborations have also been announced this year.

In March, the Export-Import Bank of China announced a first loan cooperation with Saudi National Bank, Saudi Arabia’s largest bank, in yuan.

Hong Kong has also been named as a major hub for financial cooperation between China and Saudi Arabia.

In July, the Hong Kong Monetary Authority, the city’s de facto central bank, signed a memorandum of understanding with the Saudi Central Bank, pledging initiatives in financial infrastructure development, open market operations, market connectivity and sustainable development.
