Taiwan's interior minister has confirmed two senior executives from the Hong Kong-listed company China Innovation Investment Limited have been detained by authorities over allegations relating to election interference. Xiang Xin and his wife Gong Qing, who are executive director and director of the company, were stopped at Taiwan's Taoyuan Airport on Sunday while trying to leave the country. It follows explosive claims by self-confessed spy Wang Liqiang, who told Australia's Nine Network that the company provided a cover for espionage, with Xiang acting an alleged ring-leader of the operation.
