TikTok has been dealt a devastating blow as a US bill has been signed into law forcing owner ByteDance to sell within a year or face its removal from app stores. 

The stakes are higher than in 2020—China's opposition to a divestment will make an optimal sale harder to conclude, so all sides must be prepared for a ban.   

The TikTok bill introduces extraordinary new powers in the context of the US and China's broad systemic rivalry, though online consumer benefits will be limited.  

The US is intent on preventing the CCP’s goal of AI supremacy by 2030, banning exports of advanced AI chips to Chinese companies. So far, these bans have largely been shrugged off to create a new commercial dynamic in the region. 

Huawei wields a de facto monopoly on the manufacture and sale of advanced chips in China. Huawei also sells cloud services globally and threatens Apple's $70 billion in Chinese revenues through its premium handsets. 

China’s AI regulation is highly supportive of the training and deployment of Chinese-language LLMs developed by tech platforms, startups, and device makers, with meaningful revenue gains only appearing by H2 2024. 

After China updated its Anti-Monopoly Law to cover platform companies, the Government is bringing to heel privately owned ‘national champions’, including via antitrust measures in their home market—the key source of their astronomical cash flow—and through interference in their expansion outside China

China lacks any tradition of anti-monopoly activity, given its gradual shift to the market from state-owned enterprises, it offers an example of theory in practice for antitrust reformers targeting platforms in the West

The global implications are huge: up to $2 trillion of Wall Street shares are exposed as China tightens controls on foreign IPOs. Regulators could also use enhanced antitrust powers to disrupt global dealmaking for economic leverage
