"We cannot expect a change in the hostile policies of some of our geopolitical opponents in the immediate future," Putin said, without elaborating on the countries he was referring to.
"The reasons for pressuring Russia are clear: the country is conducting an independent policy and doesn't trade its sovereignty. This is not to everyone's liking, but it can't be any other way," he said.

Putin pointed to what he called attempts to split Russian society "to find the weak link," but maintained that they had not yielded the desired results. Those attempts came from those who introduced and continue to support "restrictive measures" against Russia, the president said.
Russia should look into all challenges it now faces and define the strategy of the country's national security, Putin said.
"It is necessary to quickly analyze the entire spectrum of potential challenges and risks - political, economic and informational, and others, and on this basis to adjust the strategy of the national security."
Putin's statement comes after the Pentagon unveiled its new military strategy where it said that Russia, North Korea and Iran are among its new challenges together with non-state groups - particularly the "violent extremist organizations" such as Islamic State and the Taliban.
