As relations with China worsened, Sihanouk pursued rapprochement with the US. He learned that Kennedy's widow, Jacqueline Kennedy, had expressed a desire to see Angkor Wat. Seeing this as an opportunity to restore relations with the US, Sihanouk invited her to visit Cambodia and personally hosted her visit in October 1967. Jacqueline Kennedy's visit paved the way for Sihanouk to meet with Chester Bowles, the US ambassador to India. To Bowles, Sihanouk expressed his willingness to restore bilateral relations with the US, hinted at the presence of Viet Cong troops in Cambodia, and suggested he would turn a blind eye should US forces enter Cambodia to attack Viet Cong troops retreating into Cambodia from South Vietnam—a practice known as ""hot pursuit""—provided that Cambodians were unharmed. Silhanouk told Bowles that he disliked the Vietnamese as a people, saying he had no love for any Vietnamese, red, blue, North or South". Kenton Clymer notes that this statement "cannot reasonably be construed to mean that Sihanouk approved of the intensive, ongoing B-52 bombing raids" the US launched in eastern Cambodia beginning in March 1969 as part of Operation Menu, adding: "In any event, no one asked him. ... Sihanouk was never asked to approve the B-52 bombings, and he never gave his approval." The bombing forced the Viet Cong to flee from their jungle sanctuaries and seek refuge in populated towns and villages. As a result, Sihanouk became concerned that Cambodia might get drawn into fighting in the Vietnam War. In June 1969, he extended diplomatic recognition to the Provisional Revolutionary Government of the Republic of South Vietnam (PRGSV), hoping that he could get the Viet Cong troops under its charge to leave Cambodia should they win the war. At the same time, he also openly admitted the presence of Viet Cong troops in Cambodia for the first time, prompting the US to restore formal diplomatic relations with Cambodia three months later.
