The United States paid $4.5 million to design a port infrastructure programme at Callao, the US State Department said on November 12, 2026. Callao is Peru's busiest port, and Peru is moving its main naval base there to expand it.
The port sits less than 80km up the coast from Chancay, a Chinese-controlled megaport. The State Department disclosed the payment in a note on a trip to Peru and Colombia earlier in November 2026 by Thomas DiNanno, undersecretary for arms control and international security, whose remit includes the file.
