One of the masters of Indian parliamentarism, Subramanian Swami, spoke out quite harshly about the buildup of the Chinese military presence in the Indian border area in the Ladakh region. According to S. Swami, citing data from Indian military intelligence, China transferred to the border region “a large number of” Russian-made fighters "Su". What specific aircraft modifications are we talking about?, Subramanian Swami does not report.
Member of the Indian Parliament Steering Group:
The movement by Chinese troops of a large number of Russian-made Sukhoi aircraft to the border area with India should be taken as a signal that, so that we too can be ready to respond.
According to other sources in India, to one of the high-altitude airfields in the Ladakh region, the Chinese Air Force transferred one fifth generation J-20 fighter and several Su-30 fighters (modification Su-30MK2).
Moreover, in India they say, that the Chinese military prefer to use Russian-made aircraft - the same Su-30, as "have experience of not quite successful patrolling with J-20 fighters near Indian borders".
If J-20 was okay, China, without hesitation, would throw them.
Earlier in the Indian media, citing military sources, it was announced that the Indian Air Force Su-30MKI fighters had detected a Chinese "stealth" aircraft of the new generation J-20. That is why, according to Indian experts, China and decided to give preference to Su aircraft at the high-altitude airfield.
