China had lodged a solemn representation with Washington, Chinese foreign ministry spokesman Ma Zhaoxu said, according to Xinhua.
"China firmly opposes the Dalai Lama visiting the United States and US leaders' contacting with him," Ma said.
"We urge the US side to fully understand the high sensitivity of Tibet-related issues, honour its commitment to recognising Tibet as part of China and opposing 'Tibet independence'," Ma said.
Despite political pressure at home, Obama avoided meeting the Dalai Lama when the Buddhist monk was in Washington last year, in an apparent bid to set relations off on a good foot with Beijing early in his presidency.
Obama, however, told Chinese leaders during his trip to Beijing in November that he planned to meet with the Dalai Lama, who is widely respected in the United States but branded a separatist by Beijing.
Obama also knows Chinese support is vital if he is to succeed in winning unanimous backing at the UN Security Council for the tough regime of sanctions he wants to impose on Iran for stepping up its suspect nuclear work.
Next week's meeting in Washington comes at a time when relations have already soured over the sale of a 6.4-billion-dollar package of US weapons to Taiwan, which Beijing regards as a Chinese territory.
Beijing last week said it "resolutely opposes" the planned visit by the Dalai Lama, who fled Tibet into exile in India in 1959, especially any meetings with US leaders.
The Dalai Lama, 74, fled his homeland after a failed uprising against Chinese rule. That came nine years after Chinese troops were sent to take control of the region.
