Meanwhile, China's firm commitment to the denuclearization of the Korean Peninsula reached through peaceful means has remained consistent.

Fu has been keeping a close eye on the issue for years. She was personally involved in the multiparty efforts at the early stages, through which the Three-Party Talks evolved into the Six-Party Talks and then broke down.

Her article, The Korean Nuclear Issue: Past, Present and Future, released by the John L. Thornton China Center of the US think tank the Brookings Institution in April 2017, is of great help in understanding the nuclear issue.

The article chronologically summarizes progress since the signing of the Korean War armistice in July 1953 to the time when the US and the Republic of Korea announced the deployment of the Terminal High Altitude Area Defense (THAAD) missile system in ROK in July 2016.

It also details China's actions since it started to mediate the issue and host talks in 2003 to the time of the China-US summit in Florida and the first round of the China-US Diplomatic and Security Dialogue in June 2017.

During the latter event, China further explained to the US its proposal of "double suspension". This, as Chinese Foreign Minister Wang Yi says, proposed that the DPRK suspends its missile and nuclear activities in exchange for a halting of large-scale US-ROK military exercises, as well as a dual-track approach to denuclearizing the peninsula while establishing a peace mechanism.

China also reiterated its opposition to the deployment of THAAD at the event.
