Jesper Hornskov, a resident birder in China who has led a number of trips involving Irish birders, is organising trips to Manchuria and Yunnan in late 2010 and Spring 2011. Jesper's knowledge of China is unique - he has the largest Chinese list of any birder - and he is an excellent guide.
The trip lists from previous trips are far too good to list here but needless to say the quality of birding is superb (and afterwards you may never want to bird NI again!).
