The Asia Reassurance Initiative Act of 2018, signed into law on December 31, 2018, includes several sections relevant to U.S. policy toward North Korea. These include:
A Sense of Congress supporting trilateral security cooperation between the U.S., South Korea, and Japan
A requirement that, if the executive branch terminates any sanctions with respect to North Korea, the Secretary of State shall submit a report to Congress justifying the termination.
Requirements of regular reporting to Congress on threats posed by North Korea, U.S. negotiating strategy, and efforts to improve international sanctions enforcement.
A Sense of Congress that the U.S. should advocate for North Korea's expulsion from all international organizations until it meets the denuclearization commitments expressed in various UN Security Council resolutions, and that the U.S. should work to induce countries to meet their commitments to enforcing the sanctions imposed by those resolutions.
An expression of support for efforts to improve information access in North Korea.
