Germany has welcomed the extension of talks between Iran and six world powers until November 24, hoping that the two sides would reach a final deal within the extended period of negotiations.

In a statement on Saturday, German Foreign Minister Frank-Walter Steinmeier said all sides had "very serious negotiations” in recent months over Iran’s nuclear energy program and were able to achieve “significant progress."

He said the two sides have the impression that "the differences can still be overcome in the time remaining” so that a final deal would be reached.

According to Press TV, Steinmeier added that differences still remain between the two sides but Germany has agreed with other countries from the group of six world powers that it would be wrong to stop the negotiations.

Iran and six world powers – the US, France, Britain, Russia, China and Germany – have agreed on the extension of talks on Tehran’s nuclear energy program until November 24 with a view to achieving a permanent deal that would end the decade-old dispute over Iran’s nuclear energy program.

The two sides sealed an interim deal in Geneva, Switzerland, on November 23, 2013, for a six-month period. The deal, which took effect on January 20, expires on Sunday.

Under the deal, dubbed the Geneva Joint Plan of Action, the six countries undertook to provide Iran with some sanctions relief in exchange for Iran agreeing to limit certain aspects of its nuclear activities.
