“A team of Defence Research and Development Organisation inspected the consignment and certified that it could be used by the neighbouring country for its nuclear program,” officials said.

“A Karachi-bound ship from China was stopped by Indian security agencies at Mumbai’s Nhava Sheva port on suspicion that it contained a dual-use consignment that could be used for Pakistan’s nuclear and ballistic missile program,” officials, in Mumbai, said on March 2.

The customs officials, based on an intelligence input, halted a Malta-flagged merchant ship — CMA CGM Attila — at the port en route Karachi on January 23 and inspected the consignment, which included a Computer Numerical Control (CNC) machine, originally manufactured by an Italian company.

CNC machines are basically controlled by a computer and produce a scale of efficiency, consistency and accuracy not possible manually.

“A team of Defence Research and Development Organisation (DRDO) also inspected the consignment and certified that it could be used by the neighbouring country for its nuclear program,” officials said.

According to the experts, the equipment would be useful in manufacturing critical parts for Pakistan's missile development program.

Since 1996, CNC machines have been included in the Wassenaar Arrangement — an international arms control regime aimed at stopping the proliferation of equipment with both civilian and military uses. India is among the 42 member countries that exchange information on transfers of conventional weapons and dual-use goods and technologies. The CNC machine was used by North Korea in its nuclear program.

“The port officials, with specific intelligence, had alerted the Indian defence authorities who inspected the heavy cargo and reported their suspicions, after which the consignment was seized,” the officials said, adding that the seizure falls under the prevention of possible proliferation by Pakistan and China.

According to documents such as bills of loading and other details of the consignment, the consigner was mentioned as "Shanghai JXE Global Logistics Co Ltd" and consignee was "Pakistan Wings Pvt Ltd" of Sialkot.

“However, a deeper investigation by the security agencies indicated that the consignment, weighing 22,180 kg, was shipped by Taiyuan Mining Import and Export Co Limited and was meant for Cosmos Engineering in Pakistan,” the officials said.

This is not the first instance when Indian port officials have seized such dual-use military-grade items being shipped from China to Pakistan.

Cosmos Engineering, a Pakistani defence supplier, has been on a watchlist since March 12, 2022, when Indian authorities intercepted a shipment of Italian-made thermoelectric instruments, once again at the Nhava Sheva port.

The officials said there have been concerns that Pakistan might be utilising China as a conduit to acquire restricted items from Europe and the U.S., masking identities to evade detection.

Concerns have intensified over Chinese support for Pakistan's nuclear and missile programs, exemplified by a 2020 case where an industrial autoclave, crucial for missile production, was concealed as industrial equipment on a Chinese vessel bound for Pakistan.

The ongoing investigation aims to determine if the suspected Pakistani entities receiving these dual-use items are supplying these to the Defence Science and Technology Organisation (DESTO), responsible for much of Pakistan's defence research and development.

‘Despite assertions of commitment to international conventions by both Pakistan and China, the interception of such covert shipments underscores a persistent cooperation in potential proliferation activities, contravening global agreements and regulations,” the officials said.

In February 2020, China was supplying autoclave to Pakistan under the cover of "industrial dryer". The autoclave was seized from a Chinese ship, Dai Cui Yun, carried a Hong Kong flag and had left Jiangyin port on the Yangtze river in Jiangsu province of China, bound for Pakistan's Port Qasim.

The seizure of the autoclave, possibly meant to be used in the missile program of Pakistan, strengthens apprehensions that Pakistan is unabashedly indulging in illegal trade of missiles and violating the Missile Technology Control Regime (MTCR).

In June 2023, the U.S. Bureau of Industry and Security (BIS) sanctioned three Chinese companies — General Technology Limited (autoclave supplier to Pakistan), Beijing Luo Luo Technology Development and Changzhou Utek Composite Company — for its involvement in supplying missile-applicable items to Pakistan's ballistic missile program.
