After New Zealand's general election in 2017，a coalition government consisting of the Labour Party and the Priority Party replaced the former governing government of the National Party.In a short period of eight months，the joint government has realized the remolding of the New Zealand internal and foreign policy.Now，the housing policy is more stringent on the internal policy，the immigration policy is tightened，the education policy is paid more attention，and the sound of the Pacific affairs is emphasized to protect the national independence and interests；the policy is to put forward a rule based view of international system and “the Pacific resetting” strategy to deal with the so-called “strategic anxiety” of the coalition government，but the liberalist position on the international hot issue has not changed essentially.The change in New Zealand's internal and foreign policy highlights the concern and response of New Zealand to the increasingly complex Pacific situation，which has also basically determined the choice of New Zealand in China-US relations—on the premise of maintaining New Zealand's independent diplomatic system，the strategy continues to cooperate with the United States.Cooperation and vigilance at the same time will be the normal feature in the future Sino-US relations.
