According to one historical account, Tea Banh was actively sought out by the invading Vietnamese forces' hierarchy in the wake of Pol Pot's fall. Banh was believed to be taking refuge somewhere just over the Cambodian-Thai border on the Thai side during much of the period of Democratic Kampuchea's short-lived, but violent rule, and the fact that the Vietnamese had even known of his identity and relevance to them would suggest that they indeed had a clear and well established military and inside intelligence within the regime that they had initially given birth to, which however, had subsequently opted to part company with Hanoi and to ally with China instead.
From this snap shot of Banh's background alone it is reasonable to assume that, unlike most of other former KR defectors now fronting the current CPP regime, including [the late] Chea Sim, Hun Sen, Heng Samrin [all came from DK's designated Eastern Zone, as well as a group of the so-called 'Khmer-Vietminhs', previously exiled in Vietnam with Pen Sovan among its best known name, who had now returned to the country of their birth, Banh's apparent, deep-rooted loyalty and value to the Vietnamese at the time  or since would serve to strengthen the suspicion and argument of those who feel that Hanoi had maintained more than mere passing interest in the KR as its former sister movement and protégé.
It is also interesting to hear Banh recently made reference to Vietnam as representing an 'obstacle' to the Cambodian opposition's perceived attempt to overthrow the current Phnom Penh regime. Given that this same opposition possesses no armed forces or tanks to defeat the military under Banh's command, he and the CPP leaders might be looking at a scenario where a popular mass protest, possibly backed by splits and defections from within his own CPP's ranks, will have yet again been put down by military intervention from across the border to the east? - School of Vice
