The issue was raised by Congress leader Jyotiraditya Scindia who said People's Liberation Army had transgressed the border on land and by air in Chamoli district earlier this month when its men stationed themselves 200 metres inside the Indian territory.
Scindia, who was supported by his party colleagues, expressed surprise that neither the Home Minister nor the Prime Minister chose to clarify on the serious matter.
Noting that Uttarakhand has a 350-km long border with China, Roy called for immediate steps to check such transgressions.
SP chief Mulayam Singh Yadav used the ocassion to caution the government about the intentions of China which he described as "dhokebaz desh" (deceitful country).
"It is a deceitful country. When it is down it will keep mum, but when it is strong it will create problems," said Yadav, noting that he had also been a former defence minister.
Parliamentary Affairs Minister Ananth Kumar said that for the government the security of the borders and the unity and integrity of the country is above everything.
Concurring with opposition leaders, he said Indian army was second to none in valour. He said he would bring the issue to the attention of the ministers concerned.
