Marape said Papua New Guinea had been transparent, and when he visited Beijing this year with his ministers “there was no conversation on security”.

“We keep them in the space of the economy, we went with traditional security partners for security,” he told a resources investment conference in Sydney.

PNG signed a defence agreement with the US in May, and struck a security deal with Australia last week that Marape said was focused on internal security, including boosting police numbers and the judiciary.

“These two are complementary. External security with the USA, and internal security with Australia,” he said.

The resource rich but largely undeveloped nation north of Australia is seeking to boost foreign investment and trade to boost its economy, amid increasing jostling influence in the region between the US and China, which signed a security pact with neighbouring Solomon Islands last year.

Marape said improving security was important for foreign investors.
