National flags of Vietnam, US and DPRK flown in Son Doong cave

Notably, the image of the national flags of Vietnam, the US and the Democratic People’s Republic of Korea (DPRK) appeared in the world’s largest cave Son Doong and other tourist spots as a symbol of peace and friendship and good blessing for the second DPRK - US summit, being held in Hanoi.

“The national flags stand out on the beautiful and peaceful natural scenery, showing the belief that Vietnam is the absolutely correct choice for the significant event. This is also the way we express the happiness of welcoming the Summit in Vietnam,” said Mr. Nguyen Chau A, Director of Oxalis Adventure Tours.

Here are some images of the national flags of the three countries taken by Oxalis:
