Time for a hint, Ellinas. Asia is rather large, you know. <smile>
The country it is located is one of the largest of the world in land area.
Is it a government building in China, Ellinas?
If it's one of the largest in Asia, and it's not China, perhaps it's Russia?
Hmmm. My online source shows Russia to be the biggest in land mass, but then we are looking for only the Eastern side, I guess.
Methinks we need another clue, Ellinas.
I already gave you 2 hints. What else can I say?

It is related with Russia in many ways.
To summarize; it's in Asia, it's one of the largest landmass, and it's not China or Russa.
India?
Hey, Walter. That is ninth in places with the largest land mass according to my online atlas.
Walter appears to be correct. The Ministry of Finance building in Astana.
That's it, it is your turn.
Whose turn? Ticomaya's or Walter's?
Tico's - I didn't name the place completely.
