Event

9/19/2005

After their fourth round of Six-Party talks, the six parties issue a joint statement outlining principles for achieving verifiable denuclearization of the Korean Peninsula. The DPRK agrees to abandon "all nuclear weapons and existing nuclear programs." The statement outlines compromises on the provision of light-water nuclear reactors and other energy assistance to the DPRK, U.S. security guarantees, normalization of diplomatic relations between the DPRK and the United States and Japan, and the negotiation of a peace treaty. Follow-up negotiations stall almost immediately, however, particularly after the U.S. Treasury Department's September 2005 designation of Banco Delta Asia (BDA), a bank in the Chinese territory of Macau, as a financial institution of primary money laundering concern, due to suspected counterfeiting.

2/13/2007

The six parties reach an agreement to begin the initial 60-day phase to implement the 2005 Joint Statement. North Korea agrees to disable all nuclear facilities and provide a "complete and correct" declaration of all its nuclear programs, in exchange for the delivery of heavy fuel oil and removal of the United States' Trading with the Enemy Act and State Sponsors of Terrorism designations. Separately, the United States assures North Korea that it will return frozen funds from Banco Delta Asia to North Korea, which it does later in 2007. IAEA inspectors return to North Korea in July 2007 to monitor and verify the shut-down, install seals, and monitor facilities at Yongbyon, and maintain a continuous presence there until mid-April 2009. During this nearly two-year period, agreement on verification measures prove elusive, contributing to tensions that ultimately lead to the Six-Party Talks' collapse.

The United States and North Korea separately announce agreement on a number of items. North Korea commits to a long-range missile testing moratorium; a nuclear testing moratorium; a moratorium on nuclear activities, including uranium enrichment at Yongbyon; and a return of IAEA inspectors to the Yongbyon nuclear facilities. Separately, the United States announces that the two countries would hold further talks to finalize details of a 240,000 metric ton food assistance program. U.S. officials indicate their hope that collectively these steps will pave the way for a return to denuclearization under the Six-Party Talks process.

Less than three weeks later, however, the "Leap Day agreement" begins to unravel. On March 16, 2012, North Korea announces that it would launch an "earth observation satellite" in April, in violation of UNSC resolutions. During their talks, U.S. officials reportedly told their North Korean counterparts that the United States would regard a satellite launch as a violation of the agreement the two sides were negotiating. After North Korea proceeds with the launch on April 13, the United States suspends its portion of the Leap Day arrangement. Thereafter, North Korea follows suit.

Kim views nuclear weapons as a key component of regime survival and a deterrent against outside threats."

• "Recent demonstrations with new shorter range systems such as the new submarine and land launched ballistic missiles capable of threatening the Republic of Korea and Japan are concerning. North Korea's recent missile testing and development. They demonstrate that with sufficient time, technology, and testing, North Korea can overcome design deficiencies or other malfunctions, increasing the threat these systems pose to the region and advancing Kim Jong Un's goals against the continental United States."

President Trump and North Korean leader Kim Jong-un meet in Singapore, the first-ever meeting between leaders of the two countries. Trump and Kim issue a brief joint statement that consists of four main points:

1. The two sides "commit to establish" new bilateral relations;

2. The two sides agree to work to build "a lasting and stable peace regime";

3. North Korea "commits to work toward complete denuclearization of the Korean Peninsula"; and

4. The two sides will work to recover the remains of thousands of U.S. troops unaccounted for during the Korean War.

Speaking at a press conference without Kim after the summit, Trump says:

• U.S.-North Korea denuclearization negotiations would resume at an early date;
• Kim pledged to destroy a "major missile engine testing site";
• While nuclear negotiations were ongoing, the United States would suspend annual U.S.-South Korea military exercises, which Trump called "war games" and "provocative." He said the move, which reportedly surprised South Korea and U.S. military commanders, would save "a tremendous amount of money." Trump also expressed a hope of eventually withdrawing the approximately 30,000 U.S. troops stationed in South Korea.

Neither the joint statement nor Trump's remarks include details about a timeframe or verification protocols for denuclearization, or a commitment by Kim to dismantle North Korea's ballistic missile program.

Section 210 states that:

• it is U.S. policy to continue to impose sanctions on North Korea. If North Korea-related sanctions are terminated on an entity, the act requires the executive branch to submit a report to Congress justifying the termination.
• it is U.S. policy that the objective of nuclear and missile negotiations with North Korea is "the complete, verifiable, and irreversible dismantlement of such [nuclear and ballistic missile] programs."
• it is the sense of Congress that the United States should advocate that North Korea be expelled from all international organizations until North Korea meets the requirements imposed by U.N. Security Council resolutions.

President Trump issues an accompanying "signing statement," noting his potential constitutional objections to that several of ARIA's provisions, including Section 210.

• It is "my firm will to establish a new bilateral relationship … build a lasting and durable peace regime and advance towards complete denuclearization…. Accordingly, we declared at home and abroad that we would neither make and test nuclear weapons any longer nor use and proliferate them, and we have taken various practical measures. If the U.S. responds to our proactive, prior efforts with trustworthy measures and corresponding practical actions, bilateral relations will develop wonderfully at a fast pace through the process of taking more definite and epochal measures."
• "… But if the United States persists in imposing sanctions and pressure against our Republic, we may be compelled to find a new way for defending the sovereignty of the country…."

Speaking of inter-Korean relations, Kim says that the two countries "entered into a completely new stage" in 2018 by effectively committing to a "nonaggression declaration." He calls for replacing the Korean War ceasefire with a "peace mechanism" and says "we maintain that the joint military exercises with foreign forces, which constitute the source of aggravating the situation on the Korean peninsula, should no longer be permitted and the introduction of war equipment including strategic assets from outside should completely be suspended."

In the report Kim announces a new "offensive for frontal breakthrough" to seize the initiative as North Korea endures an "arduous and prolonged struggle" caused by "hostile forces." Kim says, among other items:

• The current U.S.-DPRK "stalemate" is due to the United States' failure to withdraw its "hostile policy toward the DPRK" and its policies "to completely strangle and stifle the DPRK" including the conduct of U.S.-ROK joint military drills "which its president personally promised to stop," shipping "ultra-modern warfare equipment" to South Korea, and continuing to impose sanctions on North Korea.
• dSue to the U.S. posture, "there is no ground" for North Korea to continue to maintain its unilateral moratorium, a "commitment to which there is no opposite party."
• "The world will witness a new strategic weapon to be possessed by the DPRK in the near future," implying a return to the country's byungjin line of simultaneously pursuing economic development and nuclear weapons by saying that "nothing has changed between the days when we maintained the line of simultaneously pushing forward the economic construction and the building of nuclear force."
• The United States cannot be expected to lift sanctions, and that "if the U.S. persists in its hostile policy towards the DPRK, there will never be the denuclearization on the Korean peninsula and the DPRK will steadily develop necessary and prerequisite strategic weapons for the security of the state until the U.S. rolls back its hostile policy towards the DPRK and lasting and durable peace-keeping mechanism is built."

Kim's report emphasizes economic self-sufficiency and autarky, and—in contrast to his usual New Year's speeches—makes no mention of inter-Korean relations.
