China's smart cities streets ahead, but same AI challenges apply the world over

Each night in the darkest hours, a fleet of drones patrols the eastern Chinese city of Nanjing, watching over potentially dodgy areas such as underground station exits and the riverside to deter any would-be criminals.

The nightly routine has been operating since last year, according to a report published in April by the city's police bureau, which detailed its use of
artificial intelligence to plan patrol routes.
According to the report, the AI puts a laser focus on patrolling Nanjing's blind spots – the areas generally ignored by human patrols.
The city's experience is part of China's efforts to scale up the use of AI in urban management, to better handle complex challenges brought by the massive scale of city life and rapid urbanisation.
The Chinese leadership has long viewed AI as a tool for transforming the economy and refining its governance, launching the
'smart cities' initiative and other programmes over the past decade.

Despite this rapid progress, analysts warned that China's AI governance faces challenges – including privacy protection and limited community involvement – that are mirrored in other parts of the world as governments race to adopt the technology.

Texas governor signs bill banning Chinese citizens from buying property in the state

A bill to restrict property ownership in Texas by Chinese citizens became law, more than two years after it was first introduced, setting up what could be a prolonged legal and political battle as critics plan to file a suit challenging its constitutionality. Advertisement Governor Greg Abbott, a Republican, announced on Saturday that he had signed the bill, which also targets nationals from Iran North Korea and Russia , into law. Abbott expressed support for the bill in February, writing on social media that the legislation 'would prohibit hostile foreign entities from purchasing land in Texas, and that 'we must get this to my desk this session'. The bill restricts individuals, companies, and government entities from China and the other named countries from purchasing property in the state, exempting US green card holders and citizens. It takes effect on September 1. The initiative allows those who hold valid US visas to purchase property, but only if the property is used as a primary residence. That means nationals from the four countries would not be able to purchase investment properties. Texas Governor Greg Abbott. Photo: The Dallas Morning News/TNS
