VIENNA, July 6 (Xinhua) -- The stake holders of the Iranian nuclear deal on Friday jointly announced that they would keep Iran in the deal by securing Tehran's interests under the deal.

Foreign ministers from China, Russia, France, Britain, Germany and Iran met in Vienna on Friday to discuss how to save the landmark deal after U.S. announced withdrawal.

A joint statement made by all parties involved in the meeting called for the survival of the nuclear deal reached in July 2015 in Vienna. The statement sent a positive signal, while the meeting was shadowed by Iran's dissatisfaction with EU's offer to secure its economy interest by anti-sanction measures.

Iranian President Hassan Rouhani said Thursday that the proposal package offered by the European Union (EU) does not secure Iran's interests in the 2015 international nuclear deal.

Rouhani said Tehran would stick to the deal only if Iran's interests are secured by the stake holders, as U.S. is re-imposing tough sanctions on Iran.

Until last month, Tehran has been cooperating with the International Atomic Energy Agency (IAEA) under the deal.

But the Iranian president said Iran would decide the level of cooperation with the UN nuclear watchdog.?
