RANCHO MIRAGE, Calif. (AP) -- President Barack Obama's national security adviser says the president described for China's leader the types of problems the U.S. has faced from cyber intrusions and theft of intellectual property.

White House national security adviser Tom Donilon gave no specifics but says Obama also underscored for Chinese President Xi Jinping (shee jihn-peeng) that the U.S. has no doubt that the intrusions are coming from inside China.

Donilon says Obama requested that the Chinese government "engage" on the issue and also understand that that type of activity is inconsistent with the kind of relationship U.S. desires to build with China.

Donilon addressed reporters Saturday after Obama and Xi concluded two days of meetings at a resort in Rancho Mirage, Calif.
