I think that definitely more tourists should come to these countries that want to see raw, beautiful nature and blooming islamic culture. If you go to Uzbekistan, you can follow the trails of the Silk Road in Samarqand, and if you go to Kyrgyzstan you can hike on the Tian Shan (Celestial Mountains). Obviously, all of these countries have interesting history due to them being part of the Ancient Chinese Empire, having islamic influence and having a history in the soviet union as well.
Just a little tip from me to you if you are looking for an interesting, empty place to go on vacation.
And...I'm not Uzbek, Turkmen, Tajikistani, Kyrgyz, Kazakh, Afghan or Pakistani. Just an Austrian guy trying to give you a "secret tip" for your next holiday.
