For training. The career that you can develop after receiving the PhD can have strong tension to t ...
You have raised two issues:
1) No one would deny that 3 yr master program can give student better preparation for PhD study than 2 or 1 yr master program can do. However, do you know how many % of master student would like (or qualified) to go for another 4 years of PhD study--less than 15% in overall (or much less). For those simply want to have a master degree but not PhD student, it does not make sense to have them consumed their 1 or 2 more years (opportunity costs) for so-called PhD preparation which is not necessary for them at all.
2) On the other hand, the time frame for a full time PhD program is usually 4 years. For a student who have qualification and competence to do a PhD program, 4 whole years is already long enough to pick up whatever needed to complete his/her dissertation. Of course, from some professors' perspective, they quite welcome those with "better preparation" chinese students, because they can have "cheaper research labour force" for 4 whole years while those from US, UK or other western would unlikely do that (or not so well-prepared to do that). However, when we look at the passing rate of PhD in US, UK or other western universities, there is no clear advantage from Chinese students over others.
From my own view, I would like to min. the opportunity costs to those Master students, and request those Master student, who want to study further to PhD program, to work more harder in their next 4 years school life.
