Once completed next year, the pole would be the tallest in the world with 189 metres in height. The world's tallest pole - with 171 metres in height, is in Jeddah, Saudi Arabia.
The "Thailand World Tallest Flag Pole" project is initiated by people of Chiang Rai, to commemorate the first centennial anniversary of Thailand's national flag as well as to create a new tourist attraction in the province which is part of the Golden Triangle. Aside from the pole, the location will house a national flag museum.
Chiang Rai deputy governor Akham Sukphan would reveal the project update at the inauguration ceremony on Monday.
