President Donald Trump said on Friday the United States would impose the “largest-ever” package of sanctions on North Korea, intensifying pressure on the reclusive country to give up its nuclear and missile programs.

“Today I am announcing that we are launching the largest-ever set of new sanctions on the North Korean regime,” Trump said during his speech at the Conservative Political Action Conference. “The Treasury Department will soon be taking new action to further cut off sources of revenue and fuel that the regime uses to fund its nuclear program and sustain its military by targeting 56 vessels, shipping companies and trade businesses that are assisting North Korea in evading sanctions.”
