(ECNS) -- When Chinese crane manufacturer Shanghai Zhenhua Heavy Industries Co., Ltd. (ZPMC) made its first sale to the United States in 1994, it had never expected that the country would regard the cranes it produced as a pain in the backside three decades later.

In February, U.S. President Joe Biden announced that the administration will invest over $20 billion into U.S. port infrastructure over the next five years. The measures, including replacing all Chinese-made cranes at U.S. ports with homegrown ones, aim at eliminating the so-called potential "national security risks" posed by "cellular modems" suspected of espionage found on the cranes, claimed U.S. media.
