Troubled Chinese property developer Kaisa’s firing of three staff from suitor firm Sunac China Holdings has thrown the planned takeover by the latter of the former into further question, South China Morning Post reported, citing an internal notice that had appeared in the media. A Kaisa official cofirmed the contents of the circular, though both firms declined to comment. The mainland real estate outfit, still struggling to repay US$10 billion in debt after the government in Shenzhen blocked sales of projects there, said the ban had been lifted last week and reinstated founding chairman Kwok Ying-shing on Monday, sending its bonds higher.
