Chinese activity near Ladakh is "eye-opening" and some of the infrastructure being created is alarming, a top US General has said.

General Charles A Flynn, Commanding General, US Army Pacific described it as "destabilizing and corrosive behaviour" by China as he talked about the Chinese infrastructure build-up across the Himalayan frontier.

"I believe that the activity level is eye-opening. I think some of the infrastructure that is being created in the Western Theatre Command is alarming. And so much, like across all of their military arsenal, one has to ask the question, why," the General, who oversees the Asia-Pacific region, told a select group of journalists.

General Flynn said China's ''incremental and insidious path, and destabilising and corrosive behaviour" projected on to the region was "simply not helpful".

''I think it is worthy of us working together as a counterweight to some of those corrosive and corrupted behaviours that the Chinese [demonstrate]," said the General.
