As Gary Milhollin (of the Wisconsin Project on Nuclear arms control) Puts it..
“If you subtract Chinese assistance from the Pakistani nuclear weapons program, there is no program".
Lol
Now, ostensibly in November 2014 after the announcement that Iran was about to sign a deal with Western negotiators concerning its nuclear program(the date of which was later extended) an ex Chinese ambassador to Tehran, Hua Liming said that it was Beijing which deserved credit for brokering the agreement. “When the two parties came across irresolvable problems, they would come to China, which would ‘lubricate’ the negotiation and put things back on track"- Hua's statement.
China has not just helped Pakistan and Iran in their nuclear programme but also rogue states like North Korea.
Since North Korea and Iran 're not an immediate threat to india, we should not really be concerned bout 'em.
But let me take your attention to something more important, that while China was ready to help Pakistan with technology, they were not ready to fund it. So who pumped money into Pakistan's nuclear programme???
Not hard to guess!!
Pakistan used some
civilisational logic to raise funds
. I can't take names here.Ahem!!!
I can just give a hint that "this is how China came close to the Arab world"
.
So you see, Pakistan has more than one partner-in-crime.
Sorry to rain on your party but let me clear a few doubts here
1) North Korea itself gets help from China,so whatever help Pakistan gets from North Korea (as you think) is nothing but China's help to you (directly or indirectly).
2) flashback 1970's:
Check Bhutto's diaries to know how many trips he made to China between 1971 and 1976 to get some assistance in nuclear weapon technology??
He went thrice to China!! (I can't say about other pawns in the game).
China took its time to assess the prospects and consequences of helping Pakistan and finally agreed.
