It would be nice if Asian countries were more rigid when it comes to visitors. I like the way the Bhutan handles travel to their country. It's restricted. There are rules:

Travel to the Kingdom of Bhutan is highly regulated under the policy "High Value, Low Impact Tourism" in order to minimize the impact on the country's unique society and environment.
