Which country?

Think of a country:

It is as Europian as Asian, but sometimes referred as Middle Eastern. In fact it is not far from Africa, and also has very deep relations with America.
All Central Asia are their very close relatives, and Balkans has their cultural extensions.
We should mention that with Arabs and Persian they have blood relation also, we shouldn't forget Russians and Armenian.
Although this country considered as an Islamic country; Christian, Jewish and fire-worshippers live together and peacefully.
Sometimes they appear in 'Black Sea Economic Cooperation', sometimes in NATO and BM, sometimes in 'Euro-mediterranean Partnership', sometimes in 'Organisation of The Islamic Conference'.

That's right; it's Turkey, of course :)
