The China Securities Regulatory Commission's approval comes amid heightened geopolitical tensions between the world's two largest economies. The Biden administration published a sweeping set of export controls on Friday, seeking to hobble China's chip industry. Huatai-PineBridge made the application for regulatory approval on Aug. 9.

The exchange-traded fund (ETF) will invest in top Korean semiconductor firms including Samsung Electronics Co and SK Hynix Inc, as well as Chinese chipmaking giants such as Semiconductor Manufacturing International Corp and Montage Technology Co.

"The Chinese and Korean semiconductor industries are expected to be closely integrated," creating synergies, Huatai-PineBridge said in prepared marketing material for the ETF, whose launch date has not yet been determined.

The fund will also benefit from China's accelerated pace towards tech self-sufficiency amid U.S. sanctions, according to the marketing material, which mentioned the U.S. blacklisting of China's Huawei Technologies Co Ltd, and the recently enacted CHIPS and Science Act.

In 2021, South Korea was China's second-biggest exporting country in equipments, including chipmaking tools, and Chinese exports to South Korea have also been rising, the fund manager said.

South Korea said on Saturday there would be no significant disruption to equipment supply for Samsung and SK Hynix's existing chip production in China from the U.S. move.

The new U.S. export controls are an abuse of trade measures, China's foreign ministry spokesperson Mao Ning said on Saturday.

The newly approved ETF will track the CSI KRX China-Korea Semiconductor Index.

The index was launched as part of a broader cooperation agreement signed last year between the Shanghai Stock Exchange and the Korean Exchange (KRX) to promote cross-border investment between the two markets.
