Sources said that the matter will also be raised at the next border meeting between Indian and Chinese officials.
Chinese troops entered nearly 1.5 kilometres into the Indian territory near Mount Gya, which is recognised as the international border by India and China, and painted the word 'China' in Cantonese on the boulders and rocks there with red spray paint, sources said.
The incursions were reported from the area generally referred in the Chumar sector in east of Leh.
The 22,420 ft Mount Gya, also known as 'fair princess of snow' by the Army is located at the tri-juction of Ladakh in Jammu Kashmir, Spiti in Himachal Pradesh and Tibet.
Its boundary was marked during the British era and is regarded as International border by the two countries.
