I've just read that Chinese police officers are on the beat in Rome and Milan. Only a few for now, but chances are more are on the way. They are there to give the Chinese tourists a greater sense of security - one of Italy's efforts to woo Chinese business. Will we soon see Chinese police keeping the queue moving and making sure that their group gets in first? How much does Italy, or Europe, want that business?
The last time I was in Bath, I couldn't get near the Abbey. In the end I just took pictures of the courtyard full of Chinese tourists.
When I was in graduate school, I had a Chinese classmate who used to joke that there were spies planted among the Chinese students to make sure they behaved correctly or risked being sent home. Now that they are wearing uniforms, people who are wary of them at home seem grateful to see them abroad.
My Chinese friend married a nice Jewish girl from Philadelphia. I don't know how his government felt about that. Maybe they would have intervened had he been an engineer instead of a sociolinguist.
