Because of rising US-China tension and tougher US listing regulations on overseas (including China) firms, many China firms plan to delist their shares from the US market and to list their shares on the HK and Swiss exchanges. Please provide your insights on the following questions:

China Mainland has well-established stock exchanges, such as Shanghai and Shenzhen exchanges. Why do China firms need to list their shares outside China Mainland?

Does Swiss exchange provide a good and favorable channel for China firms to list their shares there?

Will delisting of China firms in the US market benefit Hong Kong?
