A huge investment, of economic and geo strategic in nature between china and Iran came in to shape. Recently, these two countries announced an agreement which signed for the next 25 years, the cost of this agreement is $400 billion dollars china spends $400 billion in Iran oil and gas, petrochemical, transport, and energy related manufacturing for the next 25 years. Under this deal Iran will give oil to China at low prices for the next 25 years; in revenue, China will invest a massive amount to stabilize Iranian economy and infrastructure. Along with that, China will cooperate with Iran in the technological, industrial, energy and scientific sectors. This is an important development for the Iranian economy which is under severe strain due to the US sanctions. The 25-year deal will bring huge benefits to Iran, which has been one of the world’s largest oil producers, but its exports, Iran’s biggest source of profits, He has fallen after being US imposed sanctions on Iran on his nuclear deal.China is currently proposing a large investment in oil imports from Iran. This will brings both states in win win situation. Along with that, According to some reports, China plans to build many ports in Iran, through his string of pearls policy one of which is located in Jask outside of the Strait of Hormuz. This will give China a strategic advantage over the waters through which India and most of the world’s oil transit. In the context of India, China’s Iran growing relationship and this close ties are worrying for India because of before five year, India and Iran signed an agreement to build a railway line from the port of Chabahar to Zahedan along the border of Afghanistan. But a few days after the agreement were declared, the Iranian government stated to keep on with the construction on its own, and after that Iran decided India would be removed from the Chabahar project. India was to build a railway track from Chabahar to Zahedan, but it late from the Indian side in funding and starting the project. The Narender Modi’s administration failed to deliver funds for the project, Iran has started it on its own. Further, China and Iran finalized this massive 25 years deal, $400 billion strategic partnership deal with Iran. Along with that, the oil transit lane the Strait of Hormuz is one of the important chokepoints. The Strait of Hormuz is among the key nine maritime chokepoints across the world China strategy to build some ports in Iran through strait of harmuz. Rising china paths in Iran will have a long-term effect on Indian relationship not only Iran but also on Afghanistan and some others central Asian countries. Moreover, as mention earlier this agreement does not seem well for India and it can only hurt India’s interests in the region this is very difficult for India it brings negative impact on Iran and India relations. This deal is not good it any coast for India; India is facing many hurdles of her economy. It is a massive challenge for India’s economy. A few years ago, India was big buyer of the Iranian oil but it was stopped by India because the US imposed sanctions on Iran for its nuclear program. They both were faced economic hurdles after this decision and now this deal will brings more tension for India and and it will also put at risk India strategic interest in Indian Ocean and Persian gulf. Furthermore, India’s investment in the Chabahar port aimed to compete with Pakistan’s Gwadar port and to counter this port but China’s presence in the region now greatly hinders India’s political interests in the region. Furthermore, India has traditionally had a non-alignment policy in international disputes. Over the years, the behavior of the ultra-nationalists in the Modi administration and his racist policies has influenced India’s foreign policy. Similarly, from the Pakistan perspectives growing china Iran relationship, Pakistan can use the current situation to push India is an invisible direction. The deal has had major implications for Pakistan in many ways. For example, in the past India has used Iranian land against Pakistan. Therefore, the withdrawal of India from some major projects in Iran is a progress for Pakistan. Pakistan realizes that India’s non-existence on Iranian land is directly proportional to Pakistan’s peace and stability. In this regard, Pakistan needs to take a proactive approach to Iran and ensure a smooth relationship, especially in the future conditions of Chabahar and Gwadar ports. Gwadar is an important project of the China-Pakistan Economic Corridor, and China’s goal is to invest in Chabahar Port. In this way, Pakistan can work to complement each other at both the ports. Pakistan can take advantage of Sino-Iranian relations not only to improve its fragile economic situation, but also to increase India’s majority in the region.To this end, Pakistan needs to increase more regional interests and take advantage of India’s weaknesses.
