Although, OIC's web-site says:
The Organization is the collective voice of the Muslim world and ensuring to safeguard and protect the interests of the Muslim world in the spirit of promoting international peace and harmony among various people of the world.
... it is mostly a silent organization. We don't see much from OIC other than passing some periodic Tweets and trivial statements.
Among others, Pakistan and Iran are members of OIC.
- OIC is mostly silent in the matter of Kashmir. Last year UAE invited Indian FM to the OIC's summit even though India annexed Kashmir and kept Kashmir under lockdown ever since.
- Iran and Saudi Arabia are regional rivals and follow different sects of Islam. For years, Iran has been working in undermining the monarchy. Recently, Saudi Arabia blocked Iran from participating in an OIC meeting.
Why are Iran and Pakistan members of OIC? What benefit does it serve to them?
