Mainland China adviser calls for ‘unilateral opening up’ to Taiwan for faster unification, cites Cold War West Germany
Zheng has been widely seen as an influential adviser to the top leadership after his appearance in 2020 at an economic and social policies symposium of Beijing’s decision-making Politburo, chaired by President Xi Jinping. He is also a member of the Hong Kong Chief Executive’s Policy Unit Expert Group, formed last May.

Beijing sees Taiwan as part of China to be reunited by force if necessary. Most countries, including the United States, do not recognise Taiwan as an independent state but Washington opposes any attempt to take the self-governed island by force and is committed to supplying it with weapons under its Taiwan Relations Act.
Warning about Washington’s “very dangerous cognitive war” on the Taiwan issue in recent years, Zheng suggested that Beijing counter it with better “socioeconomic and cultural exchanges” across the Taiwan Strait, while its People’s Liberation Army could just “keep an eye on things”.
Calling on both sides of the strait to achieve peaceful unification and avoid historical tragedies such as war, Zheng said mainland China should learn from the West German policy during the Cold War, which treated those coming in from East Germany as citizens with equal rights.
“This is a very good [model] and [we can adopt it] to encourage cross-strait exchanges,” he said, adding that the mainland should take the initiative on this.
“Since we regard Taiwan as a province, that’s all the more reason for us to implement a unilateral opening up to Taiwan,” said Zheng, who is the dean of the new public policy school at CUHK-Shenzhen.
Citing the concept of the “cross-strait common market” – as proposed by former Taiwanese vice-president Vincent Siew Wan-chang – Zheng also called for Taiwan to be included in what he called the “southern China common market”, with the Greater Bay Area at its core and integrating the mainland coastal provinces of Hainan and Fujian, as well as the also proposed China-Asean common market.
Zheng became the first mainland academic to openly advocate for “unilateral opening-up” by Beijing, when he called for allowing more unilateral visa-free travel to the mainland in 2021, following prolonged border closures over the Covid-19 pandemic.
