In 1977, the leftist US President Jimmy Carter signed a treaty to grant the Panamanians control of the canal as long as they guaranteed its permanent neutrality.
However, panama government has likely violated the treaty recently on neutrality: They gave their operating rights of two ports (Balboa and Cristóbal, which sit on the Pacific and Atlantic sides respectively, ) to Communist China’s company which is the Hutchison Port Holdings since 1999!
The communist china is a rival or an enemy of USA! The Trump’s Administration considers that is a violation of treaty!!!
Hutchison Port Holdings is a subsidiary of CK Hutchison Holdings owned by Hong Kong businessman Li Ka-shing. As we know that almost all Hong Kong and Chinese Companies are direct or indirect controlled by the communist China - that is an open secret for everyone!
