The White House says that, during telephone talks this week, Obama told Chinese President Xi Jinping that the two sides have to enhance their communication and coordination to make progress on the North Korean nuclear issue.
Obama also said their bilateral relationship should be defined by increased practical cooperation and the constructive management of differences.
This could indicate the two superpowers might expand their existing communication channels or add an additional line to enhance cooperation.
Multi-lateral dialogue, known as the six-party talks, used to be the main line of communication dealing with North Korea's nuclear weapons program, but they haven't been held since 2008.
Experts say Washington is well aware of the severity of the North Korean nuclear issue and is trying to encourage Beijing to pressure Pyongyang to come back to the negotiating table.
U.S.- China relations have become increasingly strained in recent months amid maritime disputes in the South China Sea, accusations of cyber espionage, human rights issues as well as their strategy on North Korea.
Obama and Xi are scheduled to meet in Beijing in November at an Asian Summit.
