The sanctions will undoubtedly hurt the already-isolated North Korean economy.
North Korea has accused the US and South Korea of escalating tensions by conducting military drills.
The UN resolution condemned North Korea for the "massive diversion of its scare resources" towards developing nuclear weapons, noting UN findings that well over half of its population was facing lack of food and medical care.
