On the Contrary, if not Indians then somebody else like China, Russia or EU will fund Chabahar. This is infact bad news for Gwadar. The Central Asian landlocked states, China and Russia can get a safe access to sea through Iran rather than the precariously risky and dangerous AfPak.
Iran will become the main Player in the region in the Great Strategic Game. And this diminishes the so called "importance of Pakistan" for regional peace and stability.
This Iran deal is Bad Bad news for Pakistan. The Saudis are furious with this deal. Pakistan is in catch 22. The Relationship with Iran and Pakistan speak for themselves.
India is laughing all the way for its gambit of putting some of its eggs in Iranian basket during sanctions will pay off. Expect the two way trade between Iran and India jump exponentially...be it in energy and infrastructure. I bet now China will also trade more with Iran than Pakistan. Your CPEC will be put on secondary and the primary focus of China will be Iran for its energy security.
Pakistan could loose its importance for China vis a vis Iran.
This is Pakistan's worst nightmare ... Iran's dominance in the region ... strategic, economic and even cultural.
Good News for India, China, Russia ... Bad news for Pakistan, Saudi Arabia.
