Iranian Interior Minister Mostafa Pour Mohammadi arrived in Beijing on Thursday for two days of talks that he said would focus on the debate over his nation’s nuclear program.

Negotiations are the best way to resolve the dispute over Iran’s nuclear program and China supports efforts to continue the contact between Iran and the European Union (EU), the Chinese top envoy in Vienna said on Wednesday.

The Tehran stock exchange has broken its record for the highest ever transaction on the bourse with the sale of shares worth over one billion dollars in a state copper company.
