How to educate bachelor and master exchange students from Asia?
I teach at a university in Asia and I could say the exact same thing about our European/American exchange students. 

Quite simply, exchange students have very different incentives from regular students. They often convert their grades to a simple pass/fail on their transcripts so they just need to pass the class (we get students from very reputable institutions in the US Canada and Europe, I was surprised to hear about that practice at first). In addition for many of them it’s their first time in a new and exotic location. They want to party and travel. With all due respect, lectures are the last thing on their mind.

Some of the exchange students are hard working, but I would say that they are a minority. 

To conclude I think your question has a bit of a cultural bias to it. European students can be equally annoying in an exchange program.

Edit: the question is biased because it seems to attribute this behavior to the students’ “Asian-ness” rather to them being in an exciting foreign country, away from their parents, dealing with a new language and academic practices, and all that within a few weeks. All of the bad practices the question describes can be easily observed in European/American students who come on exchange to my Asian university. Also, lumping together all students from Asia (or even just India/China) is completely inaccurate, and an over generalization of a group of people constituting the majority of humankind. I would suggest that the OP revisit their own beliefs and consider the circumstances under which they observe this group.

By the way, we also get exchange students from China and India. Surprise! they do fine in general, because to them our university/location is not particularly exciting or different! It’s like if an American student had a semester in the UK. Sure it’s different, but a lot of things are the same. Have you considered that option?

Edit 2: (reflecting OP's edit and discussion below)

There are, of course, cultural differences between Students from different cultural backgrounds. By and large, students from China tend to be quieter and ask less questions (this is especially true for female Chinese students in my experience). There are several great suggestions in the comments and in other answers: listen to them, do not be confrontational, try to schedule office hours where these students might feel more free to interact with you. 

With all this out of the way: I think that the solutions offered above are not quintessentially unique to handling Asian students. They are excellent approaches to handling any reserved student, regardless of their background. 

Moreover, exchange students (American, European, Asian or African) tend to be  more difficult than regular students (as I describe above). This is a far more important factor in this equation than the cultural parameter from my own limited experience. 

I think it's great that the OP is looking to improve their teaching, I just don't think that the difficulties have so much to do with cultural differences as they do with the universal difficulties that arise with foreign exchange students.

As an aside, there are some comments in the threads that are very close to sounding like "I'm not racist, but...". In my opinion, that is unfortunate.
