In Malaysia's case the civilian long-range surveillance radars are SSR only, with a range of 200 NM; there is no primary radar. The major airports (eg KL, Kota Bharu) generally have a 60 NM primary surveillance radar collocated with a 200 NM SSR. An approach controller could see you on primary radar at short range if they knew where to look, but they'd be blind to anything outside 60 NM.
