I know this is an old thread (apologies for bringing it back up again), but have you tried making your own? There are plenty of Chinese recipes on websites online (my favourite recipe databases are taste.com.au and bbcgoodfood.com)
From the first website mentioned, I searched "low kilojoule" and "Chinese" under advanced search, and came up with 32 recipes. These include (although I'd calculate the calories- or nutritional information to suit your diet- on some of these myself, some of them look a little unrealistic) Chinese fried rice, pork and Asian greens stir fry, Chinese roasted pork with stir-fry vegetables, plum and ginger chicken, chilli jam scallops with Asian greens, Asian pork with wilted Asian greens, Hoisin lamb, and ginger tofu with mushrooms. (For calorie ratings, take the number under "energy", which is in kilojoules, and divide by 4.2- and/ or calculate this on a recipe calorie calculator)
On the second website, I search under "refine your recipe search". Oddly, they don't have a "Chinese" search, although I've made a couple of Chinese foods from that site. But you can search in terms of calorie range (again I'd recommend recalculating that yourself as I find this website to be a little optimistic), "under 200", "200-400", "400-600", "600-800", or "over 800". I've made "Chicken & Mango Stir Fry" and "Beef Stir-Fry with Ginger" that are Chinese-ish from their site.
Hope this helps (you and/ or others who might come across it).
