According to BBC Persian, in light of Ahmadinejad’s inauguration the European Union has indicated that they will not congratulate Ahmadinejad for his presidential victory. Members of the EU have justified the decision to be as a result of the harsh reaction of the government of Iran to the demonstrations.
Typically, the EU would have sent a letter on the occasion of Iran’s inauguration ceremonies.  Ahmadinejad clearly flouted the EU decision in his inauguration speech, however, saying: “not congratulating me is an insult to the vote and the systemic organization of our nation” and “no one is waiting for your praise, the people of Iran don’t care for your criticisms nor do they care for your praise.”
The United States also did not send a congratulatory letter to Ahmadinejad.
