With the world about to descend on Shenzhen, China is tightening up to ensure people that would “cause harm” to the country are kept out. When you add the Jasmine Revolutions sweeping the Middle East and high inflation in China, you can see why those in Zhongnanhai might be a little jittery.

We told you earlier that foreigners are being warned to ensure they have all the proper paperwork to live and work in Shenzhen. But the government certainly isn’t picking on laowai: it is also ridding Shenzhen of anybody else it doesn’t like prior to the games. From the China Daily:

Shenzhen has ejected about 80,000 “potentially unstable people” in a bid to secure social stability for the upcoming 26th Summer Universiade, the Shenzhen Economic Daily reported.

Shen Shaobao, vice director of Shenzhen Police Bureau announced the figure from the “100-days Social Security Campaign” during a news conference.

“People living in Shenzhen without proper identity, justifiable reasons and those acting suspiciously posing a threat to people and the social security are what we called unstable residents,”said Shen.

Eight groups of people are listed in the high-alert category, including former inmates, nomads, unemployed vagrants, people engaged in suspicious activity including drug trafficking and contraband goods. Since January police have also removed people who live by fraudulent means such as child-beggars, mentally ill people who pose a danger to others, and unregistered residents who earn money in the rental business and unclassified floating residents.

The Public Security Bureau is getting good at this, having done the same in Beijing in 2008 and Shanghai and Guangzhou in 2010. The question is, what does the Universiade think about it? The Wall Street Journal tried to find out:

Neither Shenzhen police nor the International University Sports Federation, the Belgium-based organization that puts on the Summer Universiade, responded to written requests for comment from The Wall Street Journal. It’s unclear where evicted residents were transferred and how officials determined which mentally ill residents posed a threat to public safety.

If you are an “undesirable” or an “unemployed vagrant”, best to lay low until October.
