"This is a situation that we are following closely and carefully. I'd have to refer you to the governments of India and China for more information on that," State Department Spokesman Heather Nauert told reporters at a news conference.
Responding to a question, she said the Indians and Chinese are talking on those issues.
"They're going to talk to one another," she said ahead of the Beijing visit of the National Security Advisor Ajit K Doval to attend the BRICS meeting on July 27 and 28.
"We would encourage them to engage in direct dialogue aimed at reducing tensions," Ms Nauert said.
China, however, said yesterday that diplomatic channels with India remained "unimpeded" to discuss the military standoff but reiterated that the withdrawal of the Indian troops from Doklam area is a "precondition" for any meaningful dialogue.
Chinese and Indian soldiers have been locked in a faceoff in Dokalam area in the southernmost part of Tibet in an area also claimed by Indian ally Bhutan for over a month after Indian troops stopped the Chinese army from building a road in the disputed area. China claimed it was constructing the road within its territory, and has been demanding immediate pull-out of the Indian troops.
