CHINA’S three biggest telecommunications firms said they requested a review of the New York Stock Exchange’s decision to delist their shares more than a week ago, a move triggered by an executive order issued by former U.S. President Donald Trump.

The drama surrounding the delisting, which played out over a few days with the bourse at one point reversing the decision before enforcing it again, caused wild swings in the companies’ stock as investors were left with little time to react to the various moves. It also prompted some global equity indexes to remove the securities.

In separate filings Thursday to the Hong Kong stock exchange, where they’re also listed, China Mobile Ltd., China Unicom Hong Kong Ltd. and China Telecom Corp. said that written requests had been filed with the New York Stock Exchange (NYSE) and that they’d also asked for trading suspensions to be stayed while the review is undertaken.

The review will be scheduled at least 25 business days from the date the request is filed. There’s no assurance the review request will be successful, the companies said.

In its communications around the delistings, the NYSE indicated it was acting to comply with an executive order issued by Trump, barring investments in companies deemed by the Trump administration to be linked to China’s military.

The announcement of the review requests came hours after Joe Biden was sworn in as Trump’s successor in Washington on Wednesday.

The Trump administration had been ramping up its attacks on China the past few months. The United States had also sought to sever economic links and deny Chinese firms access to American capital, an escalation of its moves over tariffs as part of the trade war. (SD-Agencies)
