You are thinking of Modi here. Like he sealed his lips ever since Galwan defeat, he has kept his mouth firmly shut.
He has not uttered China's name once.
Pakistan on the other hand gave China its claimed territory other side of Mount Goodwin.
Why it has left it open because the issue of Ladakh should be negotiated once Kashmir is liberated. It would go according to the claims and historical data.
And according to the plebiscite. The plebiscite is the entire essence and basis of that agreement.
