China deployed its embassies to spread doubts about the performance of French-made Rafale jets after they saw combat in India and Pakistan’s clashes in May, French military and intelligence officials have concluded, implicating Beijing in an effort to hammer the reputation and sales of France’s flagship fighter.

Axar.az informs findings from a French intelligence service seen by The Associated Press say defense attaches in China’s foreign embassies led a charge to undermine Rafale sales, seeking to persuade countries that have already ordered the French-made fighter — notably Indonesia — not to buy more and to encourage other potential buyers to choose Chinese-made planes. The findings were shared with AP by a French military official on condition that the official and the intelligence service not be named.

Four days of India-Pakistan clashes in May were the most serious confrontation in years between the two nuclear-armed neighbors, and included air combat that involved dozens of aircraft from both sides. Military officials and researchers have since been digging for details of how Pakistan’s Chinese-made military hardware — particularly warplanes and air-combat missiles — fared against weaponry that India used in airstrikes on Pakistani targets, notably French-made Rafale fighters.

Sales of Rafales and other armaments are big business for France’s defense industry and help efforts by the government in Paris to strengthen ties with other nations, including in Asia where China is becoming the dominant regional power.
