KUALA LUMPUR (Nov 21): Petronas Dagangan Bhd's share price fell the most among the 30 FBM KLCI stocks in afternoon trades today after the KLCI's early plunge below the 1,600-point level, as US-China trade spat uncertainties hit world markets.

Reuters reported that global stocks took a beating on Thursday, as a fresh row between Washington and Beijing over US legislation on Hong Kong threatened to undermine their trade talks and delay a "phase one" deal that investors had initially hoped to be signed by now.

"The US House of Representatives on Wednesday passed two bills intended to support protesters in Hong Kong and send a warning to China about human rights. The legislation, which has angered Beijing, has been sent to the White House for President Donald Trump's approval. A person familiar with the matter said Trump was expected to sign it," the newswire said.

At Bursa today, Petronas Dagangan's share price fell 54 sen or 2.24% to RM23.62 at 3:12pm. The counter is the leading percentage decliner among the 30 KLCI components. Top KLCI decliners include AMMB Holdings Bhd and RHB Bank Bhd.

In the broader market, the KLCI was down 11.43 points or 0.71% at 1,589.71 at 3.44pm. Earlier today, Petronas Dagangan's share price fell as much as 80 sen or 3.31% to RM23.36.
