China’s rare admission raises stakes

China has admitted its engineers supported Pakistan’s J-10C fighter jet operations during India’s Operation Sindoor in May 2025, a disclosure that adds a sharper China angle to the India-Pakistan conflict.

The admission came through Chinese state broadcaster CCTV, where AVIC engineer Zhang Heng described being at a support base as fighter jets took off and air-raid sirens sounded. He said the team worked in extreme May heat while trying to keep Chinese-made equipment combat-ready.

Why the J-10C disclosure matters

The J-10CE, Pakistan’s export version of China’s J-10C multirole fighter, is central to the story because Pakistan remains its only foreign operator. The aircraft is linked to advanced AESA radar and PL-15 long-range air-to-air missiles, making any wartime support politically sensitive.

Indian defence officials have said Operation Sindoor targeted terror infrastructure after the Pahalgam attack, while later briefings claimed 13 Pakistani aircraft and 11 airfields were hit. Those claims, combined with Beijing’s acknowledgement of technical support, are likely to intensify scrutiny of the China-Pakistan defence partnership.

Regional security impact

The timing is significant. The disclosure surfaced around the first anniversary of Operation Sindoor and reinforces India’s long-held concern that Pakistan’s military capability is increasingly backed by Chinese systems, engineers and supply chains.

For New Delhi, the key question is no longer whether Chinese weapons were used, but how deeply Chinese personnel supported Pakistan during active conflict. That makes this admission more than a defence update—it is a fresh flashpoint in Asian security.
