Sister cities

Twinned with Port Moresby

1 of 2 in this atlas

Port Moresby's atlas entry lists a single twinning, with Jinan, China, and this pairing is mutual: each city names the other in return. No further partnerships appear in this dataset, so Port Moresby's recorded civic ties, at least as documented here, extend to this one relationship rather than a wider network of paired cities.
