Good summary of how this Ladakh incident got started and its current aftermath.
Its already 2021. To think that everything started from this, on Aug 6th, 2019. 1 day after Article 370 was revoked.
No Indian or Western media would ever bring this speech up as the starting point of the China-India border crisis. To them India is always right, and China is always evil. Till this day the narrative has always been: "Chinese unprovoked aggression". In truth, after this speech, China and Pakistan furiously protested. It was a unilateral redrawing of the map by India, disregarding all their disputes. But so arrogantly, India and the West conveniently ignored their complaints.
1) India started the offense with the revocation of Article 370.
Then India starts building roads at the disputed area.
2) When China ceased fire in 1962, it announced that it would withdraw 20 kilometers behind the 1959 LAC. This was supposedly a more demilitarized zone for the military from the two sides to disengage. India clearly did not see the point and has over the years to build roads and military facilities very close to the Chinese side. The restraint from the Chinese side was not reciprocated.
At the same time the Indian media was doom-mongering and laughing when China was facing the Covid-19 outbreak in Wuhan. China rightly saw this as a blatant Indian attempt to change the status quo on the ground.
3) Not only that, India also saw Covid-19 was an opportunity to poach supply chain out of China and has openly engaged in activities in doing so.
So China had to respond, and responded in a big way. The PLA moved into the disputed area and occupied the Chinese claimed area. We ironically hear so much in India media about how "China is caught flat footed". Turns out it was India who was the one that was caught flat footed. India called this: Chinese aggression, Chinese invasion, intelligence failure, or whatever. But the fact of the matter is China cannot trust India anymore with regards to Aksai Chin. Thus force had to be used to draw the line on the ground first, and then negotiate a settlement. Even after that, India could never negotiate in good faith with China. It wanted the PLA out of the area, but refuse to commit to keeping Indian troops out too. Hence, the border crisis that continues to this day.
4) The big picture is that India sensed opportunity and moved to leverage the tension between the US and China, as well as Covid-19, moving closer to the US strategically against China. On top of that, it's very clear India had learned the wrong lesson from the 2017 Doklam Incident when the Indian Army moved into Chinese territory to intervene Chinese building road at the border between China and Bhutan. China showed remarkable restraint to end the standoff by stopping building activities at the site. Later on, Xi and Modi conducted two separate meetings to stablize and manage the relationship. Indian media and strategic community almost unanimously claimed victory and vindication of its "tough" China policy.
The whole premise of Chinese strategic restraint vis-a-vis India and low-profile at the border region towards India is based on India's strategic autonomy and non-alliance posture, or more specifically not joining any group against China. India clearly has misread the intention and behavior from China.
This is where we are today.
