Who was the Vietnamese diplomat who helped create the peace agreement between North Vietnam and the US?

The Vietnamese diplomat who played a crucial role in creating the peace agreement between North Vietnam and the United States was Le Duc Tho. He was a key negotiator during the Paris Peace Accords, which aimed to end the Vietnam War. Tho's efforts, along with those of U.S. negotiator Henry Kissinger, culminated in the agreement signed in January 1973, although Tho famously declined the Nobel Peace Prize awarded to him and Kissinger for their work on the accords.
