Looks like CLOB (Iskandar seems to have more consistent support from the Malaysian government) had been known to be a problematic entity since the beginning:
3 The Malaysian government's opposition to trading of Malaysian shares on Clob is long standing, and has always been reported in the press. When the SES established Clob in Jan 1990, after Malaysia unilaterally delisted all Malaysian shares from the SES, the KLSE objected strongly. It declared publicly that Clob was an unrecognised market, and warned investors of the dangers in trading Malaysian shares on Clob.
4 As recently as Aug 98, the National Economic Action Council of Malaysia called for the closure of Clob. The SES responded that Clob would remain viable only so long as there is demand from investors for its services. This exchange was widely reported in the press, and put investors on notice of Malaysia's intentions.
