By "article", do you mean Wikipedia?
Did you notice that the only sentence in which Pakistan's "concern" is mentioned, there is no citation? In fact, the only citation in that entire paragraph is a statement by Nehru in the Indian parliament.
The most relevant sections though, are cited (below) and also, keep the context of these developments in the 50s and 60s in mind, they took place after the events in '47 which were discussed before in this thread:
"By 1959, however, Chinese maps were published showing large areas west and south of the MacDonald line in China. That year, the Government of Pakistan announced its willingness to consult on the boundary question."

"After Pakistan voted to grant China a seat in the United Nations, the Chinese withdrew the disputed maps in January 1962, agreeing to enter border talks in March. Negotiations between the nations officially began on October 13, 1962 and resulted in the Sino-Pakistan Agreement signed on 2 March 1963 by foreign ministers Chen Yi of China and Zulfikar Ali Bhutto of Pakistan."

Are you seriously going there? Dude your governments get rewarded for military failures, as we've been seeing since 2019. Modi actually got re-elected after the whole Balakot fiasco. Any other self-respecting population would've booted that guy out of office for the failed bombing alone, let alone getting a Mig splashed and fragging their own chopper. Then next year, after China walked in and kicked his ass, and again no real dip in popularity. Then Modi completely messed up the Covid response and again, he's still in office.
Interesting that the negotiations started in 13th Oct 62 while the indo Chinese war started on 20th oct.
So Pakistan wasn't worried by the Chinese claims in the 50s and accepted them immediately (63 actually) ? What were the negotiations for then ? And why does the Pakistani UN recognition lead to the Chinese withdrawing the maps ?
Nothing you have written actually contradicts what i had cited.
And Pakistan did sign away a large part of its previously claimed territory to the Chinese.
About balakot was it really a failure ?
India has lost 100s of civilians and soldiers in terrorist attacks from the 90s.
Passenger train bomb blasts in the 90s in Mumbai killing 100s ,bombay stock exchange blast -the perpetrator dawood ebrahim openly hiding in pakistan. His kid getting married to the kid of miandad , a cricket legend in Pakistan.
1999 kargil attack, right after vaypayees historic visit.
Parliament attack in 2002.
2008 Mumbai attack.
And these were during the reign of our liberal Congress PM Manmohan singh.
How did India respond ? With words.
Except in kargil, where bjp vajpayee was in charge and the PA was thrown back. But even here no Indian plane crossed the LOC to attack the Pakistani positions.
The balakot air strikes were the 1st time post 1971 war that Indian planes actually bombed a non disputed part of Pakistan , not Kashmir.
Pakistan responded by releasing air to ground missiles from well within their own territory into Indian Kashmir.
For whatever reason Pakistan did not allow journalists to examine the attacked camp for 41 days. While claiming that it was a madrassa for kids. Which was under guard by the Pakistani army ?
This attack laid the groundwork for the historic abolishment of the article 370. Pakistan could do nothing except wail.
As for the Chinese. Its been discussed ad nauseam so i will just say that the first Chinese casualties at the hands of a foreign army in 40 decades. Result of a deliberate act by a enemy.
