Beijing signaled its displeasure over CK Hutchison Holdings’ agreement to sell its majority controlling stake in Panama ports to a BlackRock-led consortium, sending shares in the Hong Kong-based company sharply lower.

A commentary by Chinese state-owned Hong Kong newspaper Ta Kung Pao criticizing the deal was republished by the joint official website of the Chinese Communist Party’s Hong Kong and Macao Work Office and the State Council’s Hong Kong and Macao Affairs Office on Thursday. The piece was also reposted by China’s liaison office in Hong Kong.
