Iran's President Mahmoud Ahmadinejad said that Iran is still waiting to see "basic changes" in U.S. President Barack Obama's policies, local Press TV website reported on Tuesday.
"Actions speak louder than the words...We have yet to see Obama bring any basic changes to Washington," Press TV quoted Ahmadinejad as saying during his visit to neighboring Kazakhstan.
Tehran would reconsider ties with Washington once the U.S. sets the record straight, he said.
Ahmadinejad's remarks come as a response to Obama's recent speech in Prague, as he urged for the implementation of U.S. plan to set up a missile system in Eastern Europe as long as there was missile threat from Iran.
In his speech before cheering crowds in Prague, Obama said the United States will present Iran with "a clear choice" to cease its nuclear and ballistic missile activities or face increased isolation.
Iran's nuclear program is questioned by many parties. The United States and other western countries claim that Iran intends to secretly develop nuclear weapons, and the UN Security Council also requires Iran to suspend its uranium enrichment activity.
However, Iran insists that its nuclear plan is only for peaceful purposes, and continues its uranium enrichment activity despite pressure and sanctions from western countries.
