The coming weeks are decisive for the future of the nuclear deal with Iran, German Chancellor Angela Merkel said on Sunday, adding that every day that passes without Tehran responding to US overtures will result in Iran enriching more uranium.

Speaking during a visit to Israel, the outgoing chancellor said that Russian President Vladimir Putin and Chinese President Xi Jinping also had a responsibility to help to push Iran back to the negotiating table, she said at a joint news conference with Israeli Prime Minister Naftali Bennett.

“I also see a responsibility for Russia and China here, since if the JCPOA (nuclear deal) is no longer doing what it’s meant to do then that’s very difficult, so we are now in very decisive weeks for this deal.”

She also said that Germany believes that a two-state solution remains the best way to end Israel’s decades-long conflict with the Palestinians.

“I think that on this point, even if at this stage it seems almost hopeless, the idea of a two-state solution should not be taken off the table, it should not be buried … and that the Palestinians should be able to live securely in a state,” Merkel said.
