Ping An Insurance (Group) Co fell by the most in more than five months in Hong Kong trading after a media report that China Development Bank Corp halted loans for Charoen Pokphand Group Co's purchase of a stake in the insurer.

Ping An tumbled 4 percent, the most since July 23, to HK$68.15 ($10.81) at the close of trading. The lender called off its HK$44 billion loans in December after learning about the existence of undisclosed Chinese investors behind the purchase, Caixin Online reported on Tuesday, citing an unnamed person.
