Pakistan's weapons programs:- The latest U.S.-imposed restrictions on entities supporting Pakistan's defense programs may hinder Islamabad's future efforts to acquire sensitive defense technologies and its collaboration with China but are unlikely to affect Pakistan’s weapons development for now, experts say.

Sixteen Pakistani firms were among 26 international companies added this week to a U.S, “entities list,” making them ineligible to acquire U.S. items and technology without government authorization.

Companies or individuals can be placed on the list if they are “involved or pose a significant risk of being or becoming involved in activities contrary to the national security or foreign policy interests of the United States,” according to a U.S. Commerce Department statement.

Nine of the 16 Pakistani companies added to the blacklist this week were accused of being front companies for a previously sanctioned company, Advanced Engineering Research Organization, deemed responsible for the country's cruise missile and strategic drone programs.

The remaining seven entities were added for contributions to Pakistan’s ballistic missile program, the Commerce Department statement said. Other companies added to the list this week were accused of procuring U.S.-made items with military applications for China, Iran, Egypt and the United Arab Emirates.

Defense analysts told VOA that addition to the list is unlikely to slow Pakistan’s missile program, which has continued despite multiple rounds of U.S. curbs on entities supporting it.

“It will not make a difference to Pakistan,” said Pakistani defense analyst Salman Javed, who acknowledged that the country relies on the United States for other defense technology needs. “I believe Pakistan's missile program is in an advanced stage, and U.S. restrictions will have no impact on it.”

Former Pakistani army General Talat Masood said Pakistan has looked more to China than the United States for “the expertise and technology” needed to advance its drone program. But he said the new curbs might affect Pakistan’s future collaboration with China in the field of drones and their sale to other countries.

Pakistan has not officially responded to the latest restrictions but objected last month when Washington blacklisted four companies, three Chinese and one Pakistani, for “knowingly” transferring prohibited equipment to Pakistan. Islamabad said the sanctions were imposed “without any evidence whatsoever.”

Syed Irfan Ashraf, an assistant professor at the University of Peshawar in Pakistan, said the United States has long prevented arms technology sales in black markets to protect its interests. “However, the timing and scrutiny of entities supporting Pakistan right now is crucial” because of the conflicts in Ukraine and the Middle East.

In September, the U.S. State Department acted against five entities and one individual — all but one Chinese — that were involved in the proliferation of ballistic missiles and controlled missile equipment and technology to Pakistan.

Salman Ali, a Pakistani scholar at the School of Politics at the Quaid-e-Azam University Islamabad, said the recent wave of U.S. sanctions represents a distinct shift from the usual regulatory measures observed since Pakistan's de facto nuclearization and are aimed more at pressuring China.

“Over the past six rounds of U.S. curbs, it's clear that the focus has been on the technical exchanges between China and Pakistan. These sanctions are not only intended to curb the rapid advancement of missile and drone programs but are also seen as a strategy to pressure China,” Ali told VOA.

Pakistan and Iran are both members of the China-led regional alliance Shanghai Cooperation Organization (SCO), which opposed the unilateral sanctions in its recently concluded summit October 16 in Islamabad. VOA/SP
