China has built new structures near the site of a Himalayan border clash that left 20 Indian troops dead earlier this month, fresh satellite images suggest.
Bunkers, tents and storage units for military hardware are visible in an area where last month there were none.
Fighting between the nuclear-armed powers over their disputed frontier has prompted alarm. Chinese casualties were also reported but not confirmed.
The latest images were published as the sides hold talks to defuse tensions.
The fresh satellite images, dated 22 June, are from space technology company Maxar. The structures which appear to have been built by China overlooking the Galwan River were not visible in aerial photographs earlier in June, Reuters reported.
Neither India nor China has commented.
The clash in the Galwan Valley, in the disputed Himalayan territory of Ladakh, took place on 15 June, weeks after high-level military commanders from both nations agreed to "peacefully resolve the situation in the border areas in accordance with various bilateral agreements."
Since the clash, and amid spiraling rhetoric, the two nations have tried to publicly calm tensions.
A statement released by India's foreign ministry on Wednesday said that India's Foreign Minister Subrahmanyam Jaishankar and the Chinese Foreign Minister Wang Yi.
"reaffirmed that both sides should sincerely implement the understanding on disengagement and de-escalation that was reached by the senior commanders on 6 June". Source: BBC
