Yes, sometimes, especially with foreigners. They will be careful to do that because they are still under the surveillance of the government.
I do have some colleagues who were very politely asked by the police of China to leave the country. The leader had to write down their names and register their activities, but no arrests are taking place.
This happens in Beijing and it is happening in Shanghai. Sometimes they have activities in a hotel, and their number is 100 to 200 people. Basically they didn't register their activities with the government. They are foreign activities. They have to register first. If they are working in the open and register with the government, this can be done.
