He made the remarks in a local ceremony in the southeastern province of Kerman on Monday evening, IRNA reported.
World states have high respect for Iran and no side of the nuclear agreement is able to renege on the deal, the official added.
What is said about breaking the nuclear deal is just some propaganda to frighten the Iranian people, Jahangiri said.
Words heard about violation of nuclear deal after the change of US president are worthless declamations, he added.
The vice president noted that Iran will continue the current approach and expects removal of the rest of sanctions.
Despite restriction of resources, the government will continue progress towards development, he added.
Jahangiri said development of deprived regions of the country is the government's top priority because due to the West sanctions, the government was not able for some time to focus on development of underprivileged regions.
Iran is the safest county in the region and enemies made the Takfiri groups to destabilize the country, he added.
The official added that all powers have confessed to the fact that without Iran's help, security of the region cannot be established.
If Iran had not helped Iraq, Daesh would have been governing in Iraqi capital, Baghdad now, he noted.
