India has taken over a strategically important port in Iran, giving it a potential bulwark against China’s growing influence in the region and access to Afghanistan and Europe that bypasses Pakistan. India signed the lease on Saturday for Chabahar port in eastern Iran about 90km west of the Pakistani port of Gwadar, which is being developed by China. Gwadar is the centrepiece of a massive Chinese infrastructure programme in Pakistan and is expected to be the site of China’s second overseas military base, according to a US Department of Defence report last year.
