Early in September 1990, Vietnamese Prime Minister Đỗ Mười, general secretary Nguyen Van Linh and former Prime Minister Pham Van Dong travelled to Chengdu, China, where they held a secret meeting with Chinese Prime Minister Li Peng and General Secretary of the Chinese Communist Party Jiang Zemin. On 17 September 1990, General Võ Nguyên Giáp also made a trip to China and thanked the Chinese Government for its past assistance. Despite outward signs of improvement in Vietnam's diplomatic relations with China, Vietnamese leaders were reluctant to endorse any peace plan which could weaken their client government in Phnom Penh. However, as the four Cambodian factions reached an agreement on the power-sharing arrangement outlined at the Third Jakarta Informal Meeting in February 1990, Vietnam and China rapidly moved to re-establish formal diplomatic relations. In November 1991, newly elected Vietnamese Prime Minister Võ Văn Kiệt travelled to Beijing and met his Chinese counterpart, Li Peng, and they issued an 11-point communiqué re-establishing diplomatic ties between the two countries after 10 years without formal relations.
