Mainland search engine giant Baidu Inc. has selected CLSA Ltd. and Goldman Sachs Group Inc. for its planned second listing in Hong Kong, which could raise at least US$3.5 billion, according to people familiar with the matter.

Nasdaq-listed Baidu plans to sell shares in the Asian financial hub as soon as the first half of this year, the people said, asking not to be identified as the information isn’t public. The company could sell about 5 percent to 9 percent of its share capital, meaning the offering could raise at least US$3.5 billion based on its latest market value of almost US$70 billion.

More banks could be added and details of the offering including timing and size are subject to change, the people said. Representatives for CLSA and Goldman Sachs declined to comment, while a representative for Baidu had no immediate comment.

Baidu joins a wave of US-listed mainland firms in seeking a trading foothold in Hong Kong amid simmering tensions between the world’s two biggest economies. Companies from JD.com Inc. to NetEase Inc. raised about US$17 billion through share sales in the city last year, according to data compiled by Bloomberg.

The past week has been a whirlwind for Chinese companies trading on American exchanges. The New York Stock Exchange reversed course twice on a decision to delist three mainland telecommunications companies, while the Trump administration is now considering barring investments in the Asian nation’s two most valuable companies: Alibaba Group Holding Ltd. and Tencent Holdings Ltd.

A secondary listing in Hong Kong allows mainland firms to expand their investor base and acts as a hedge against potential delisting. US President Donald Trump has already signed legislation that could kick firms off US exchanges unless American regulators can review their financial audits, an issue that has remained unresolved between China and the US for over a decade.

Baidu has been seeking to catch up in the heated area of online entertainment, with its core search app morphing into a platform hosting a wide array of content from articles to videos. Late last year, it agreed to buy Joyy Inc.’s livestreaming mainland business for about US$3.6 billion and its Netflix-style iQiyi Inc. competes with services run by Tencent and Alibaba.
