   ​Putin: US sanctions contradict its national interests, will
backfire      “But as for sanctions, they usually have a
boomerang effect, and without a doubt will force US-Russian
relations into a corner,” he elaborated. “This is a serious blow
to our relationship. And it undermines the long term security
interests of the US State and its people.”    Boomerang effect
“The measures taken by the US administration towards Russia, in
my view, contradict the national interests of the United
States,” Putin said. “This means that, for example, large
companies wanting to work in Russia after facing certain
restrictions will lose their competitiveness compared with other
global energy companies.”  “We gave an opportunity for the
largest US company to work in the [Arctic] shelf. So what, the
States does not want it to work there?” Putin wondered. “They
are hurting their biggest energy companies. And for what? In
order to, after making one mistake, insist on making another?”
