Members of the U.N. Security Council meet Saturday in Turkey with Iranian officials about Tehran's nuclear program.
Iran's adversaries say it's working on technology to manufacture a nuclear weapon, though Tehran maintains its intentions are peaceful.
British Minister for the Middle East Alistair Burt writes in al-Hayat newspaper that Tehran during the weekend must demonstrate it is ready for meaningful dialogue.
"I doubt anyone is unaware of the urgent need for these talks," he writes. "The international community has serious and long-standing concerns about Iran's nuclear program, which the Iranian government has failed to address for many years."
Tehran maintains the right to develop a peaceful nuclear program under international treaties. The International Atomic Energy Agency has said it believed there were likely some military aspects to certain parts of the program, however.
Burt said that Tehran faces a real risk of losing its credibility in the eyes of the international community if it fails to live up to its obligations.
"We are not seeking regime change," writes Burt. "What we want is a peaceful and negotiated solution. If Iran cooperates, our offer to provide help in a number of areas, including with the development of civil nuclear power stations, still stands."
