Former President Ma Ying-jeou’s application to travel to Hong Kong for a brief speaking engagement has been turned down by the new Tsai administration. It was a decision based on consultation with government security agencies and wasn’t Tsai’s unilateral decision. Technically Ma’s application did not meet the rules regarding the 20 day advance notice for former presidents within 3 years of leaving office. Lee Teng-hui was allowed to travel to the UK one month after stepping down in 2000 (by a DPP government); but the UK does not have the symbolism that HK does (it was where the meeting between KMT-CCP took place in 1992 that gives its name to the ‘1992 consensus’), and after all, HK is quasi governed by China. Ma is in possession of huge amounts of “classified knowledge” and the potential for either purposeful or accidental disclosure of information is much higher in HK than almost anywhere else in the world. This is not to imply that Ma has or had any intention whatsoever of disclosing classified information, but given that for 8 years Ma has espoused pro-China preferences it is no surprise that most Taiwanese are suspicious of a visit so soon after he stepped down to a location that has been used as a (often clandestine) meeting place for ROC/KMT PRC/CCP officials.
A further aspect is that the KMT has demonstrated before that it is happy to bypass the duly elected government to conduct “diplomacy” with China. Then KMT Honorary Chairman Lien Chan’s “peace mission” to China in 2005, completely bypassing the DPP government, is something that the DPP wants to avoid repeating. At a time when Tsai’s government has yet to really establish its modus operandi for cross-Strait relations, it is not tactically wise to let Ma visit HK and potentially take a step in that direction. I don’t think the decision is retribution for Ma’s treatment of Chen. There may be an element of throwing a bone to deep green supporters who have already been somewhat disappointed by Tsai’s conservative, centrist manoeuvres. But overall, there are genuine security issues and particular sensitivities with Hong Kong–and Ma would presumably have been aware of this when putting in his application. I have commented on this issue for the NYT here.
