SYDNEY—Pacific nations Papua New Guinea and the Solomon Islands have signed on to a joint undersea internet cable project, funded mostly by Australia, that forestalls plans by Chinese telecoms giant Huawei to lay the links itself.
The pact signed on July 11 comes as China pushes for influence in a region Australia views as its backyard, amid souring ties after Prime Minister Malcolm Turnbull accused Beijing of meddling in the country’s affairs last year.
