Tariffs have also been proposed on Chinese-made ship-to-shore cranes to reduce reliance on Chinese equipment[4][5].

Industry Response and Challenges

• Port Authorities’ Stance: The American Association of Port Authorities (AAPA) has acknowledged the potential risks but argued there are no examples of interference to date. However, they are in cautious dialogue with the US government regarding these concerns[1][4].
• Commercial Reluctance: Commercial actors are reluctant to take actions that could cause operational or financial hardship, despite the national security risks. The industry’s deep dependence on China for port equipment, shipbuilding, and other maritime services complicates efforts to reduce this reliance[4].

Future Actions and Recommendations

• Diversifying Suppliers: Encouraging the use of critical crane components from other countries like Germany, Japan, or Switzerland to reduce dependence on Chinese suppliers[1].
• Enhanced Oversight: Ensuring that components shipped to China for assembly are done with oversight from the original manufacturers to prevent unauthorized modifications[1].
• Interagency Coordination: The Department of Homeland Security (DHS) and the US Coast Guard need to prioritize closing security gaps, especially at strategic seaports like Guam’s port, to ensure the safety and security of DoD-designated commercial strategic seaports[1].

In conclusion, the dominance of Chinese-made cranes in US ports poses significant cybersecurity and national security risks. Addressing these risks requires a multifaceted approach involving regulatory actions, industry cooperation, and a strategic shift towards diversifying suppliers to mitigate the threats posed by China’s maritime infrastructure dominance.
