Ahmadinejad made the statement on the sidelines of the Shanghai Cooperation Organization summit in Shanghai today.
"We see this [package] overall as a step forward and I've asked my colleagues to carefully consider it," he said. "God willing, we will express our views in the framework of the national interests of the Islamic Republic of Iran."
The package of incentives is backed by Russia, China, the United States, Great Britain, France, and Germany.
Earlier, U.S. State Department spokesman Sean McCormack criticized the Shanghai Cooperation Organization for inviting Ahmadinejad to attend its summit as an observer.
"Certainly, having Iran there as an observer -- Iran, the world's largest or most significant state sponsor of terrorism, again runs counter to the idea that [the Shanghai Cooperation Organization] is a group dedicated, in part, to countering terrorism in the region," he said.
The Shanghai group's full members are Russia, China, Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan. Observer countries include Iran, Pakistan, India, and Mongolia.
