Washington’s European allies must make a “quantum leap” in military spending to deter Russia, the head of NATO is expected to say Monday, calling for a 400% increase in the continent’s air and missile defense budget.

Much like the EU's 17th package that was adopted on May 20, the new measures include blacklisting more individuals and targeting the Russian shadow fleet. On the latter, the EU has targeted more than 300 vessels that the bloc believes Moscow uses to circumvent sanctions, notably the export of oil.
