Chinese manufacturer Shanghai Zhenhua Heavy Industries Co. – known as ZPMC – controls large swaths of both the global and U.S. markets for the cranes, which are key to loading and unloading cargo ships. At the same time, a U.S.-based subsidiary of the Japanese manufacturing conglomerate Mitsui E&S Co Ltd is planning to increase its domestic crane capacity to the U.S., with hopes of accessing some of the $20 billion in federal money for port infrastructure authorized across legislation signed during Biden's presidency. The announcements come after the Biden administration earlier in February warned that a state-sponsored group of Chinese hackers, known as Volt Typhoon, has been working for years to access critical maritime, aviation, mass transit and pipeline operations, in what the U.S. described as an effort of "prepositioning themselves on IT networks" ahead of a possible effort to disrupt critical functions.
