Iran and China have quietly drafted a sweeping economic and security partnership that would clear the way for billions of dollars of Chinese investments in energy and other sectors, undercutting the Trump administration’s efforts to isolate the Iranian government because of its nuclear and military ambitions. 

 

The partnership, detailed in an 18-page proposed agreement obtained by The New York Times, would vastly expand Chinese presence in banking, telecommunications, ports, railways and dozens of other projects. In exchange, China would receive a regular — and, according to an Iranian official and an oil trader, heavily discounted — supply of Iranian oil over the next 25 years. 
The document also describes deepening military cooperation, potentially giving China a foothold in a region that has been a strategic preoccupation of the United States for decades. It calls for joint training and exercises, joint research and weapons development and intelligence sharing — all to fight “the lopsided battle with terrorism, drug and human trafficking and cross-border crimes.” 
The partnership — first proposed by China’s leader, Xi Jinping, during a visit to Iran in 2016 — was approved by President Hassan Rouhani’s Cabinet in June, Iran’s foreign minister, Mohammad Javad Zarif, said last week.
