(BSS/AFP) - China is among parties interested in bidding to build two new ports on the Panama Canal, its administrator said Tuesday, despite US talk of retaking control of the vital trade route.

US President Donald Trump made the threat earlier this year, alleging that China controls the strategic waterway because Hong Kong-based CK Hutchison Holdings operates existing ports at either end -- Cristobal on the Atlantic, and Balboa on the Pacific.

The firm agreed in March to transfer control of both ports to a conglomerate led by US-based BlackRock, but the deal -- viewed with suspicion by China -- has not been finalized.

The Central American country is hoping to attract $8.5 billion in investment over the next decade to expand port capacity, and to build a gas pipeline and a new reservoir, among other projects.

In addition to new ports, the project envisions the construction of a gas pipeline and a new reservoir.

"We have to be open to participation of all interested parties," and solicit "the broadest possible competition," canal administrator Ricaurte Vasquez told journalists. He said all parties would bid on an equal footing.

He declined to speculate about a possible increase in tensions with the United States if the projects were awarded to Chinese firms in the future.

The Panama Canal Authority, which has begun meeting with interested parties ahead of the bidding process, plans to award contracts for the two terminals in late 2026 and begin operations in 2029.

Hong Kong`s Cosco Shipping Ports and Orient Overseas Container Line (OOCL) are among international players that have expressed interest -- along with Singapore`s PSA International, Taiwan`s Evergreen, German Hapag Lloyd, Denmark`s Maersk and France`s CMA Terminals.

Panama`s five main ports are all located near the canal and are operated by concessionaires from the United States, Hong Kong, Taiwan and Singapore.

The 80-kilometer canal is used mainly by the United States and China and carries five percent of the world`s maritime trade.

The United States built and operated the Panama Canal for a century before handing control to Panama on the last day of 1999.
