Key players in Singapore's liner sector said that problems in the global supply chain could continue for the next six months as the Omicron variant of Covid-19 wreaks havoc on economies throughout the world.

Speaking at the Singapore Maritime Foundation New Year Conversations event held on Thursday, the top executives of Ocean Network Express (ONE), Pacific International Lines (PIL) and PSA International suggested that the ongoing woes could likely lead to a major overhaul in supply-chain structures.

ONE chief executive Jeremy Nixon attributed the severe disruptions in the liner and logistics sector over the past couple of years to a supply shock that began with the shutdown of factories in China.
