American officials say they have gotten no formal notice from Manila following Philippine President Rodrigo Duterte's announcement of a "separation" from the United States.

"We have not received any official requests from Filipino officials to alter any of our many issues where we bilaterally cooperate," White House spokesman Eric Schultz told reporters.

"It is inexplicably at odds with the very close relationship that we have with the Filipino people, as well as the government there on many different levels, not just from a security perspective," said State Department spokesman John Kirby. "We are going to be seeking an explanation of exactly what the president meant when he talked about separation from the U.S."

The State Department said Assistant Secretary Daniel Russel would visit Manila from Saturday through Tuesday. Kirby called the trip a a "long-scheduled, long-planned" visit.

Following high-level talks with Chinese leaders in Beijing, the Philippine leader announced a military and economic separation from the United States.

美国官员说，菲律宾总统杜特尓特宣布与美国“分手”，但美国未收到马尼拉的正式通知。

白宫发言人舒尔茨说：“我们没有收到菲律宾官方要修改任何双边合作领域议题的要求。”

国务院发言人柯比说，“杜特尓特的声明不符合美菲两国政府与民间多层次的紧密关系，而不仅是安全层面。”他说：“我们会要求菲律宾方面对杜特尓特总统提出的和美国分手一说做出解释。“
