Australia, a staunch U.S. ally, also promised to keep up economic and diplomatic pressure on North Korea. Turnbull and Foreign Minister Julie Bishop said pressure had to be kept on North Korea to ensure the Korean peninsula was denuclearized. Australia has offered up a P-8A surveillance aircraft to help monitor North Korea's compliance with sanctions. The U.S. has accused China and Russia of breaching UN sanctions on North Korea by transferring oil from their ships to North Korean tankers out at sea to avoid detection. The strategy called for closer tracking of ships suspected of carrying banned weapons components and other prohibited cargo to and from North Korea.
