China’s Ministry of State Security (MSS) has provided Iran with new technology in an effort to prevent infiltration by US and Israeli intelligence, and to help Tehran defend itself from advanced US and Israeli warplanes in the case of a renewed war, according to a 10 February report by Modern Diplomacy.

The report states that Beijing is urging its ally, Tehran, to abandon US and Israeli-made software and replace it with closed, encrypted Chinese systems that are difficult to penetrate.

This includes supplying Iran with advanced Chinese sensor systems and radars, such as the YLC-8B, capable of tracking stealth aircraft and conducting electronic surveillance.

Defense Security Asia stated that according to one analyst, the “YLC-8B is one of the few radars of its type in the world which can continuously detect and track a Western fifth-generation (stealth) aircraft at long range.”

The YLC-8B was developed by China’s Nanjing Research Institute of Electronics Technology. It uses UHF-band low-frequency surveillance to undermine the effectiveness of radar-absorbent shaping used by advanced US aircraft such as the F-35 warplane and B-2 bomber. The Israeli Air Force (IAF) reportedly has 48 F-35 stealth fighter jets in its fleet.

Beijing is also encouraging Iran to transition to the Chinese BeiDou satellite navigation system as an alternative to the US-created GPS system to avoid manipulation and prevent US intelligence from using it to track Iranian targets within the country, Modern Diplomacy reported.

The report comes as the US has amassed a significant amount of its naval and air power in the West Asia region, threatening a major attack on Iran.

China is seeking to assist Tehran to protect its massive investments in Iran, made as part of a 25-year strategic agreement signed under Beijing’s Belt and Road Initiative (BRI).

Beijing also fears the loss of access to Iranian oil if Washington launches an attack, leading Iran to close the Strait of Hormuz.

Iran is China’s largest supplier of oil, while some 20 to 30 percent of the world’s crude passes through the strategic straits on Iran’s southern coast.

Despite seeking to assist Iran with new technology, Beijing has made it clear it will not intervene militarily to assist Iran in the case of a war, Modern Diplomacy noted.

China has extensive economic relations with both the US and Israel.

Instead, China is expected to limit its support to the diplomatic sphere and condemn any unprovoked US or Israeli attack as a serious violation of international law and the UN Charter.

“Beijing remains wary of sliding into a full-blown conflict that could threaten the flow of oil from the Gulf. This is what prompts it to consistently call for restraint and a return to diplomatic solutions to avoid ‘catastrophic consequences’ for the global economy,” Modern Diplomacy added.
