RASC in Shanghai

[John Mason]

My Uncle Arthur Caswell was a private in 12 mt coy RASC stationed in Shanghai in 1929. What was the RASC doing in China at that time?
A reply to: j.mason at adimage.net.au would be appreciated.

Is it possible that this was a relic of the days when, I seem to remember, Great Britain held trade concessions in Shanghai and a special "enclave" which had a British Army Garrison. Can anyone else throw more light on this ?
