The department has launched improvements to provide US citizens with clear, timely and reliable safety and security information worldwide.
Under the new system, every country will have a Travel Advisory, providing levels of advice ranging from 1 to 4.
Specifically, Level 1 is “Exercise Normal Precautions”; Level 2 “Exercise Increased Caution; Level 3 “Reconsider Travel”; and Level 4 “Do Not Travel.”
Excluding Indonesia and the Philippines, all of the other Southeast Asian countries, including Vietnam, were listed in Level 1 – the lowest advisory level for safety and security risk.
The UK, France and China were included in Level 2 – Be aware of heightened risks to safety and security.
Travellers should not visit countries in Level 4, mainly Middle East and African nations, due to the greater likelihood of life-threatening risks, according to the US Department of State.
