The Chicago Stock Exchange disclosed on Monday the investors who are backing its bid to become a bridge between US and Chinese equity markets. The proposed deal to take over a tiny US exchange has drawn outsize interest because nearly 50% of the exchange’s parent would be owned by Chinese investors. President-elect Donald Trump criticized the Chinese involvement earlier this year as he complained about the erosion of US competitiveness and trade policy. And some lawmakers have put pressure on the proposed deal, saying it could provide a way for the Chinese government to spy on US traders and other market participants. Chinese investors will own 49.5% of the exchange’s parent, The Wall Street Journal reports. The deal must be approved by the Securities and Exchange Commission.
