Panama's Supreme Court has annulled contracts allowing a Hong Kong-based company to operate container ports on the Panama Canal. The ruling comes in the wake of increasing scrutiny regarding foreign influence in the critical shipping link between the Atlantic and Pacific oceans.

CK Hutchison Holding, via its subsidiary the Panama Ports Company (PPC), has managed two of the canal's five ports since the 1990s. However, these contracts were declared unconstitutional by the court, which stated that the laws facilitating such operations were invalid.

The court's decision follows rhetoric from US officials, including former President Donald Trump, who has repeatedly stated that China is exerting undue influence over the Panama Canal. In his inaugural speech, Trump indicated a willingness to take action against such foreign operations.

Despite these claims, evidence suggesting that China directly controls the canal remains scant, although Chinese companies have a significant presence in the region.

The ruling has immediate economic implications, as CK Hutchison faces challenges with a potential sale of its global port interests to a consortium led by BlackRock and shipping group MSC, valued at $22.8 billion.

As the situation develops, APM Terminals Panama, a subsidiary of Danish shipping giant Maersk, has been appointed to temporarily oversee operations at the affected ports.

Chinese and Hong Kong officials have expressed strong opposition to the ruling, with a spokesperson stating that China will take necessary measures to safeguard the interests of its companies in Panama.
