Therein lies the difference between eastern and western cultures. Even in 90s, when Chinese armies and navies were overseas (albeit in a much smaller way), they were separated from the locals with only managed interactions. Whereas US, for example, armed forces are allowed to go out and mix with the locals. This invariably means the entertainment centres and brothels and associated conflicts. You can see Vietnam, Philippines and Okinawa as examples. While the western outlook is that these men needs to let out stress and bad things will happen if these stress are bottled. I am unable to say this also happens to Asian armed forces but traditionally those stresses are meant to be suppressed. But perhaps now it has become politically incorrect?
I'm not going to go into the political aspect however I don't think it's a bad thing for military personnels to interact with the locals during peacetime when they are out on liberty, TDY etc.
Do bad incidents happen? of course they do however I believe that in the long run it makes for good PR and it allows the locals to look at them more as 'humans' as oppose to strictly some foreign military force. The good outweighs the bad.. not to mention there is the economic aspect as well.
