Declaration of independence by Kosovo on 17th February 2008 received a mixed reaction from the Muslim world.
The following Muslim countries recognized Kosovo:-
United Arab Emirates
Being a Muslim, it was a heartiest pleasure to see a new Muslim Country emerge on the map of this world. In addition, it was somewhat healing to see Serbia being disintegrated -- the Serbia that perpetrated horrible war crimes against Bosnian Muslims, in 1980s.
It is however ironic to note that Bosnia itself has not recognized Kosovo till date. Other prominent Muslim countries that did not recognize Kosovo include IRAN and PAKISTAN
Reaction of Iran
On 13 March 2008, President Mahmoud Ahmadinejad said that Iran, after considering the region's issues and conditions, had not recognised the independence of Kosovo
In early March 2008, Gholamreza Ansari, Ambassador of Iran to Russia, said that "this question has very important aspects. Frankly speaking, the United Nations divided one of its members into two parts, though Article 1244 confirms the territorial integrity of Serbia. This is a very strange event. We think that some countries try to weaken international organizations. Presently, Iran is studying the question of Kosovo's future. Iran... expresses its concern over the weakening of international organizations"
Reaction of Pakistan:
On February 2008, the Pakistani Foreign Ministry released the following statement: "We understand and support the legitimate aspirations of the Kosovars and the need for peace in Kosovo and the region. Pakistan is watching the developments in Kosovo carefully. We have noted the recognition extended by a number of important countries to the declaration of independence by the Kosovo Parliament and the statement made by the OIC Secretary General expressing happiness over this development, and solidarity and support with the Kosovars. Our policy will be guided by these developments and the aspirations of the people of Kosovo. It remains our earnest desire that situation remains calm and peaceful in Kosovo and the region."
At a meeting on 28 January 2009 between the Kosovan Foreign Minister, Skënder Hyseni, and Mr. Shahbaz, Pakistan's Ambassador to Austria, the ambassador said that the people and government of Pakistan support Kosovo on its path. He said that Pakistan is conducting intensive talks with its neighbours and other members of the Organisation of the Islamic Conference on the issue, and that it is just a matter of time before Pakistan takes the decision to recognise Kosovo
At a meeting on 26 May 2009 between the Kosovan Foreign Minister, Skënder Hyseni, and Abdullah Hussain Haroon, the representative of Pakistan to the UN, Mr. Haroon reportedly said "finally we support your cause".
I wouldnt commnet on Iranian reaction but I fully appreciate Pakistan on this
