The world’s biggest maker of container port cranes, Chinese company ZPMC, has insisted it presents “no cyber security risk” after Republican members of the US Congress accused it of having installed suspicious equipment on cranes bound for US ports.
In a letter made public last week, 10 Republican members of Congress wrote that components including “cellular modems” had been installed on ZPMC cranes made in China before they were shipped to the US for installation.
Members of the congressional homeland security committee and the select committee on China wrote to ZPMC days after the White House announced plans to boost domestic US manufacturing of “ship-to-shore” (STS) cranes to improve security at ports.
