Several hundred dock workers in Hong Kong have marched to the offices of Li Ka-shing today, demanding better pay.
They have gathered outside the Cheung Kong Centre, demanding Hong Kong International Terminals, or HIT, increase their wages.
HIT is the largest container terminal in Hong Kong.
It's controlled by Li Ka-shing's company Hutchison Port Holdings Trust.
The company has distanced itself from the dispute, noting the workers are not Hutchison employees.
Stanley Ho is a spokesperson for the Union of Hong Kong Dock Workers.
"We hope HIT (Hongkong International Terminals) representative, to come out, to negotiate with the dock workers, especially the CEO (Chief Executive Officer) of HIT, Gerry Yim, he must come out to discuss with all the workers."
The workers are demanding a 23 per cent pay raise to make up for pay cuts they've endured over the past few years.
Subcontractors supplying labor to the port are only offering 5 to 7 percent.
Hong Kong is a major transfer point for goods flowing in and out of the mainland.
