The panel headed by Congress MP Shashi Tharoor was briefed along with other MPs by top government officials that included Home Secretary Rajiv Gauba and Defence Secretary Sanjay Mitra.
The briefing was on Sino-India boundary disputes and security, including Doklam.
Congress Vice President Rahul Gandhi also raised questions on the matter and asked officials about a recent media report showing satellite images of Chinese troop build-up near the standoff point on the Dokalam plateau.
In response, Foreign Secretary S Jaishankar said that the Chinese Army is in its own territory and similarly the Indian forces are also present on the other side.
The 73-day face-off between Indian and Chinese troops in Doklam started on June 16 after the Indian side stopped the construction of a road by the Chinese Army.
