Iran's foreign minister says the new round of nuclear negotiations with the P5+1 group of countries will be tougher and more serious. Mohammad Javad Zarif made the comments at a joint press conference with his visiting Belarusian counterpart Vladimir Makey. Zarif has noted that Iran is not expecting anything drastic to be achieved from the talks, but is hoping for progress on a range of issues including the removal of sanctions. Zarif once again expressed Iran's readiness for trust-building. The foreign minister gave assurances that Iran regards nuclear weapons as being against Islamic laws and will not change its view on the issue. Meanwhile, the visiting Belarusian counterpart Vladimir Makey hoped that a nuclear deal could contribute to the expansion of economic ties with Iran.
