The centre is hosting the APEC 42nd Transportation Working Group (TPTWG-42) meeting this week from April 4-7 with over 200 participants from 21 countries.
The facility has over 10 conference rooms including a main auditorium, a range of smaller break-out meeting rooms, a 700-seat theatre and a formal dining area. It can cater for 7000 people at one time.
The project has been delivered as a friendship venture between the governments of China and Papua New Guinea and is expected to be formally opened in the coming months.
