1. Arbitrage gone. The China arb on price has largely closed (as it should have) and its not a viable business strategy anymore for the markets I serve.
2. Vendor disinterest. Again, as it should have, the domestic Chinese market has grown such that export business in my markets is more trouble than its worth to my Chinese vendors. Those who do export find it easier to trade with Russia, China, Pakistan, and SE Asia where the technical requirements are fewer.
3. Pollution. I found myself getting sicker each time I went. I'm sensitive to smog, smoke, etc. It just became too painful.
4. Principle. As I get older I have an increasing need to trade with partners who stand for something more than profit. I want to do business with people who believe in making the world a cleaner, safer, more verdant and just place. China isn't there yet. Mercantilism, tribalism and ambition remain the dominant philosophies. I wish for Chinese leadership in a better world in my lifetime, and I'm realistic about its likelihood.
5. Hostility. I maintain a few good personal relationships where I still trade effectively. Those aside, China's prosperity and domestic rhetoric has not resulted in a kinder and gentler approach to Westerners, particularly those of us in America. I see this situation further deteriorating in the coming months and years.
