In reply to graemecook: I ve been to the region, and trekked through the Nimaling Valley, but haven't actually climbing Kang Yatze, mainly due to time and money. (I was a poor student back then!)
However, I am led to believe that it's not greatly technical, but two axes would be an advantage. Not a lot of use really I'm afraid, however, I seem to remember Martin Moran running an expedition out there, so I'm sure you could email him for info, there may even be an article on his website.
There are some photos at any rate:
