Seven Democrats led by House Minority Leader Nancy Pelosi made the first visit by US lawmakers to Tibet since anti-government unrest in 2008. The region has also been largely off-limits to foreign media and diplomats since then.
Rep Jim McGovern said the visit was an important gesture by the Chinese government but "too often" they heard characterizations of Tibet and the Dalai Lama that reflected old prejudices.
The Dalai Lama fled to India in 1959 amid an abortive uprising against Chinese rule and is shunned by Beijing as a separatist.
Pelosi, who last traveled to China in 2009, said the delegation's visit, that also took them to Hong Kong and Beijing, followed an invitation to "come see for yourself" when she raised congressional concerns over human rights with Chinese President Xi Jinping during a Washington visit in September.
McGovern said the delegation saw what Chinese officials wanted them to see in Tibet, but at Pelosi's insistence, visited religious sites too.
They came away uncertain about what steps the Chinese government was willing to take on reconciliation in Tibet, but not feeling "the door was entirely closed to anything," including to opening a US consulate in the regional capital of Lhasa.
"Some discussions were more heated than others and there were some discussions that I felt signaled openness to a constructive dialogue," McGovern said.
