The sale this week of two Panamanian ports from a Chinese company to a U.S. consortium is a victory for President Donald Trump, but it only appears to have whet his appetite for more concessions from Panama’s government.

The flash sale of a Hong Kong-owned global ports business highlights geopolitical volatility, executives and analysts said.

President Donald Trump has called for the US to retake control of the Panama Canal unless the cost of passage for naval and merchant ships is slashed. Trump’s refusal to rule out the use of force is a throwback to the 19th century era of gunboat diplomacy.
