On the first anniversary of the deadly clashes, the army said the supreme sacrifice of the soldiers while fighting the adversary in the "most difficult" high altitude terrain will be "eternally etched" in the memory of the nation.
The Indian delegation at Thursday's talks is likely to be led by Naveen Srivastava, Joint Secretary (East Asia) in the external affairs ministry, they said.
China has not yet talked about the number of casualties suffered by the People's Liberation Army during the clash.
The two sides held talks on Tuesday as well but it could not produce any tangible outcome, the sources said.
He suggested that the new structures will emerge within one year's time.
India has already mobilised fighter jets and sent thousands of additional army troops to forward locations along the border with China after 20 Indian Army personnel were killed in a brutal attack by Chinese troops in eastern Ladakh's Galwan Valley on June 15.
The Chinese military is now desperately attempting to give "ex post facto strategic meaning" to its actions in eastern Ladakh.
"The meeting thus did not result in resolution of the remaining areas," the Army said in a statement.
India and Saudi Arabia on Monday called on states to reject the use of terrorism against other countries and prevent access to weapons, including missiles and drones, to commit acts of terror.
Army Spokesperson Colonel Aman Anand said troops from China's People's Liberation Army (PLA) 'violated' the consensus arrived at during military and diplomatic engagements on the ongoing standoff in eastern Ladakh, and carried out provocative military movements to change the status quo.
In the review meeting, Singh told the top military brass to continue to deal with the situation in eastern Ladakh and other areas with "firmness".
He said both sides reaffirmed to sincerely work towards complete disengagement of the troops along the LAC.
Lauding the bravery displayed by the soldiers, the prime minister said: "The bravery that you and your compatriots showed, a message has gone to the world about India's strength."
The joint statement said Jaishankar and Wang agreed that both sides should take guidance from the series of consensus reached between leaders of the two countries on developing India-China relations, including not allowing differences to become disputes.
Singh said if there is an attempt to hurt the self-respect of India, then it will not be tolerated and will be given a 'befitting reply'. "Whatever progress has been made in the talks, there should be a resolution of the matter. But to what extent it will be resolved, I cannot guarantee."
On Tuesday, Pompeo and Esper will hold the 2+2 talks with External Affairs Minister S Jaishankar and Defence Minister Rajnath Singh, covering the entire expanse of defence and security ties as well as key regional and global issues.
