First Secretary of the Communist Party Xi Jinping will announce on Wednesday a new plan for the Greater Bay Area, which includes Hong Kong as a part of a new tech-zone with Shenzen and Macao, the Chinese propaganda outlets revealed.

Mr. Xi will visit Shenzhen today to shore up plans to make southern China a global technology hub, prompting Hong Kong leader Carrie Lam to delay an annual economic policy address.

Xi is scheduled to deliver an address Wednesday and meet the leaders of Hong Kong and Macau, the official Xinhua said Monday. The trip is intended to mark the 40th anniversary of the special economic zone that transformed Shenzhen from a primitive village to a metropolis of more than 13 million people and home to the tech companies, managed by former military, including Huawei Technologies Co. and Tencent Holdings Ltd.

Top CCP Comrade will push forward cooperation between Shenzhen and Hong Kong to a “higher level” to strengthen the key role in the Greater Bay Area, said Xinhua, without offering more details. Shenzhen will host a trial on the digital yuan and push forward with international cooperation.

The reports suggest a prominent role for Hong Kong not as a unique city but as a part of the Greater Bay Area in Communist China’s next five-year development, which is expected to be approved by lawmakers next year in Beijing, according to the reports.

Ms. Lam canceled the policy speech scheduled for Wednesday to attend the festivities and said in a briefing Monday that she now aimed to deliver it by late November after traveling to Beijing to brief Communist Party officials on her plans.

Lam’s decision shows just how much policymakers in Beijing are calling the shots in Hong Kong. Xi’s government earlier this year imposed a sweeping national security law on Hong Kong that gave Beijing the power to intervene in the legal system for the first time, prompting the U.S. to sanction officials for undermining the territory’s autonomy promised when Britain handed it over to China in 1997.
