"China is strongly displeased by and opposed to a senior US official meeting with the Dalai Lama in disregard of China's multiple representations," Foreign Ministry spokesperson Hua Chunying said.
Hua's comments came after President Barack Obama's senior adviser Valerie Jarrett took part in the Tibetan spiritual leader's birthday "celebrations" in New York on Friday.
"We urge the US side to honor its commitment to recognising Tibet as part of China and not supporting 'Tibet independence' and take concrete measures to rectify mistakes and undo any harm done," Hua said in a statement.
Hailing the Dalai Lama as a leading figure of moral and religious authority, the US Senate in a resolution recently had greeted the Tibetan spiritual leader on his birthday.
