General Lori Robinson said she anticipates a speaking engagement at China's biggest air show later this month will allow her to renew dialogue on the issue.
"The dialogue is beginning. I think that's very, very good for the region," Robinson said in a telephone interview from Hawaii.
Concerns over risky aerial engagements were spotlighted after a Chinese fighter jet came within 9 meters(30 feet) of a US Navy P-8 Poseidon plane over the South China Sea in August.
Tensions were also raised last year after China declared an air-defense identification zone over disputed islands in the East China Sea. The US, Japan and others have refused to recognise the move because the area encompassed by the zone includes territory controlled by Japan.

The ongoing feud over control of the islands has sparked fears of a collision or shoot-down, with Japan saying it has boosted jet scramblings by almost 30 percent in response to approaches by Chinese planes.
While not ruling out the possibility of future encounters like the one in August, she said it was vital that Beijing and Washington work toward an understanding.
"I never say never. What I will say is that what's important is that we do start the dialogue," Robinson said.
Robinson is the US military's first female four-star combat commander and the first woman to head the Pacific Air Forces. While most commanders have been pilots by training, Robinson's speciality is air battle management.
