Is PLA’s response to Dutch warship in South China Sea ‘putting down a marker’ for future?
Chinese military has claimed for the first time that it used ‘electronic countermeasures’ when the frigate entered disputed waters

Chinese air and naval forces had issued verbal warnings as well as using unspecified electronic “countermeasures” to “drive the aircraft away”, the People’s Liberation Army command said.
Fu Qianshao, a former air force pilot turned military analyst, said this was a “very serious form of warning” but “of course, not the most serious”.
He added: “This can involve transmitting electromagnetic signals to disrupt an adversary’s communications, radar or sensors – either through broad-spectrum barrage jamming or by targeting specific frequencies and wavelengths.”
The Dutch navy said on Thursday that the De Ruyter “had not been in [anyone’s] territorial waters” and would continue along its planned route “sailing in waters where free movement is permitted”.
