Having majority of mining power from a particular region is not a problem at all in my opinion.
I doubt this would reduce hashrate, bitcoin has survived in its early days with little of the current attention so it would adapt to any change

With increased mining centralization, and so much hashpower located in particular national jurisdictions such as China, I'm concerned about the risk of a sudden drop in hashrate. There can't be a difficulty adjustment if no new blocks are being mined. Mining could be made illegal and large farms be forced to shutdown. Would node operators agree to an emergency difficuly adjustment hardfork ?
