Until now, four countries have not fully opened up.

"Isolated" North Korea

In today's world, when it comes to isolation and isolation, North Korea is undoubtedly at the top of the list. This is the most immediate impression you have of North Korea.

North Korea has long been regarded as a land of mystery and curiosity. Even planning to travel can be extremely restrictive.

If you want to travel to North Korea, you should submit your information to the travel agency at least two weeks in advance. During the tour, you must strictly follow the route specified by the guide and cannot act alone. You can't even move around freely at night, let alone take photos.

"Unexpected" Myanmar

When it comes to Myanmar, the impression may not be good. Although the country does not seem isolated, it is actually in constant flux.

Since independence, Myanmar has chosen the path of seclusion in order to maintain internal stability and prevent external interference.

However, this path did not bring economic development to the country and resources could not be fully utilized. Eventually, the once wealthy country became one of the poorest in Asia.

"Don't want to be disturbed" Bhutan

Bhutan is not known internationally, but is consistently considered one of the happiest countries in the world. Despite this, the success rate of travel to Bhutan is very low.

Visitors to Bhutan must be accompanied by a guide at all times and cannot travel alone. The country, which is largely Buddhist, has chosen to shut itself off, fearing the impact of foreign culture on its own culture and environment.

Turkmenistan: The "Love of God"

Turkmenistan is geographically unique, located in the heart of Asia, surrounded mostly by mountains, rivers and deserts. This provides Turkmenistan with a natural barrier.

The country has chosen to sever its economic and other ties with the rest of the world and is inextricably tied to the dictatorial politics of the president.

The closed policy has prevented the full exploitation of oil and gas resources and the improvement of people's living standards.
