There are foreign students on most IOT courses and some in flying training, as well as some attending specialist training. ACSC is the Joint 'staff college' course held at Swindon polytech (Defence Academy, Shrivenham). I'm not aware of Chinese students on IOT, but sveral normally attend ACSC each year. I did foreign Staff College and we had 2 Iraqi officer - one whom had appeared on George Bush's Pack of Cards of most-wanted Iraqis. On our study trips all they wanted to find were 'the women'.
