WASHINGTON, July 8 (Xinhua) -- The United States reaffirmed Tuesday diplomacy on trying to resolve Iran's nuclear issue and said it is waiting to hear EU high representative Javier Solana's talks with Iran.

　　"This is a process that we take seriously, committed to the diplomatic resolution of this issue," State Department spokesman Gonzalo Gallegos said.

　　"I want to make very clear here that, you know, our commitment to the two-track policy stands. We are looking at, number one, carrots, and then the stick in terms of dealing with the Iranian government, of offering them an opportunity to come out of this situation, to engage more fully with the world in an open manner," he said.

　　Gallegos said the United States is waiting to hear Solana's further considerations of the recent letter from the government of Iran to him. "We will see whether or not he's able to have a further meeting with Iranian officials," he said.

　　Iran has said it is seriously studying the offer provided to it by the P5+1, or the five permanent members of the U.N. Security Council and Germany.

　　The United States has accused Iran of trying to develop nuclear weapons under the cover of a civilian nuclear program. However, Iran has insisted its nuclear program is for peaceful purposes only.
