I dont know about the size of your position but I am almost 100% positive that it is smaller than 100k. This is a 110m market cap company for gods sake, and Gurnee the CFO and not some troll in IR. We can consider ourselves lucky that a senior executive even attempts to answer questions from small shareholders during the year, this is highly unusual. Have some patience and move down the ladder. If you still dont get a response youve just witnessed common practise.
He was supposed to be back Monday, and all the people claimning to have contact with him didn't ask him a single question that didn't have an answer already, we need to know about the land they buy and be able to track the purchase, that is the ONLY way to show investors this is the real deal. Show us some papers for the US transactions with Xinyuan's name on them.
I get responses from them most time I ask qiestions and/or give suggestions in a timely manner. I guess you need demostrade to them that you are a serious long term investor. I don't think they are care short term XIN traders that much.
