HONG KONG -- The owner of a four-star Hong Kong hotel that was abruptly converted last year into the headquarters of a new Chinese national security agency said Thursday that the arrangement was purely commercial, in the company's first public comments on the deal. Jiang Hong, chairman of locally listed China Travel International Investment Hong Kong (CTI), told reporters during an online results conference that the Office for Safeguarding National Security had approached his company to lease the 266-room Metropark Hotel Causeway Bay.
