Technically you can invade if you want, but you will not be able to lay claim to anything, so it would only be a waste of soldiers.
Try building up your relations first. Promise them local support, which brings up relations 3-5 points per use. You can do that twice a year, plus you may get lucky with state visits (although those are usually rejected). Once you have relations of 25+, you can start building without any concerns and if you can get a commercial agreement with them, then even better.
But yeah, I understand your anger/frustration completely. As mentioned before, I too have lost highly expensive investments and have run out of things to invest in in Italy (until Garibaldi moves his behind that is), so you have my sympathies. I recommend you try and get in the good graces of China. They have a lot of unused potential and you could become the world's foremost silk or tea producer.
