Teheran and six world powers reached a historic nuclear deal in Vienna, Austria, on Tuesday that will enable a revitalized sanction-free Iran to boost trade and cooperation with China, analysts said.
The long-awaited agreement with China, Britain, France, Germany, Russia and the United States aims to limit Iran's nuclear program in exchange for the gradual suspension of sanctions.
The sanctions have slashed the Middle East country's oil exports and crippled its economy.
Shada Islam, policy director of the Brussels-based think tank Friends of Europe, said China could help Iran to mitigate the impact of the sanctions by providing short-term "emergency aid".
This would help to meet shortfalls in the health sector and supply urgently needed essential items.
"In the long run, the focus will of course be on the development of Iran's infrastructure and oil and gas sector," said Islam. "Given its location and diverse regional interests, Iran will also inevitably play a crucial role in China's (new) Silk Road proposal."
An Huihou, a former Chinese ambassador to Egypt, said Iran has a strong desire to participate in China's Silk Road initiatives amid Teheran's ambitious plans to revive its economy.
Closer economic links would also boost the "going global" strategy of Chinese enterprises and further elevate China's ties with other Middle East countries, An added.
Iran, a key stop on the ancient Silk Road, has joined the China-led Asian Infrastructure Investment Bank as a founding member.
Two-way trade volume reached a record $51.8 billion (S$70.5 b) last year, up 31.5 percent from 2013. The major items that China, the world's largest energy consumer, imports from Iran include crude oil and iron ore.
Iran has the world's fourth-largest oil reserves and the second-largest reserves of natural gas.
Iranian officials said Teheran is looking to return to pre-embargo oil export levels, though experts said increasing production will take time. Saudi Jadwa Investments suggested in a recent report that Iran will add just 150,000 barrels per day by the fourth quarter.
Fraser Cameron, director of the Brussels-based EU-Asia Center, said the Iranian economy has outstanding prospects because of its abundant oil and young and dynamic population. The gradual lifting of sanctions will help it to realize its potential.
"It could quickly become a major economic power in the Middle East," Cameron said. "It occupies a key geostrategic situation and could be an important hub for the new Silk Road initiatives. China-Iran relations could also develop quickly since they have complementary economies."
Li Shaoxian, an expert in Middle East studies at Ningxia University, said the reopening of the Iranian market would increase economic competition between China and Western countries. China has advantages including a rich knowledge of the local market and huge foreign exchange reserves that could be invested.
Fredrik Erixon, director of the European Center for International Political Economy in Brussels, said sanctions will probably be wound down progressively, and it will take longer than people may at first realize for business to really take off.
"But eventually, the economy of Iran can be revived," said Erixon. "China has played a crucial role in the Iran talks, and it is obvious that the world will look to Beijing for leadership in the management of the implementation process."
Measures hit banks, oil, trade
How the sanctions put pressure on Teheran:
Financial/banking: Sanctions administered by the Treasury Department in Washington sought to isolate Iran from both the US and international financial systems.
Oil exports: Before 2012, half of Iran's government revenues came from oil exports. The sanctions cut its oil exports by more than half.
Trade: The US has had an embargo in place since 1995 that prohibits most domestic companies from trading with or investing in Iran.
Asset freezes and travel bans: US allies have cooperated in freezing Iranian assets worth huge sums of money. Two years ago, Iran held an estimated $100 billion in various currencies in accounts outside the country, but Teheran could access only $20 billion.
Weapons development: The US Iran-Iraq Arms Nonproliferation Act of 1992 calls for the sanctioning of any person or entity that assists Teheran in weapons development or the acquisition of "chemical, biological, nuclear, or destabilizing numbers and types of advanced conventional weapons".
