TEMPO.CO, Singapore - The United States is encouraged by China's efforts to restrain North Korea but Washington will not accept Beijing's militarisation of islands in the South China Sea, U.S. Defence Secretary Jim Mattis said on Saturday, June 2.
The comments by Mattis, during the annual Shangri-La Dialogue, show how U.S. President Donald Trump's administration is looking to balance working with China to restrain North Korea's advancing missile and nuclear program while dealing with Beijing's activities in the South China Sea.
U.S. allies have been worried by Trump's actively courting Chinese President Xi Jinping to restrain North Korea, fearing Washington might allow China a more free rein elsewhere in the region.
Some allies have also expressed concern that Washington's withdrawal from the Trans-Pacific trade partnership and the Paris global climate accord signals the United States is diluting its global leadership role.
Speaking at the dialogue, Asia's premier security forum, Mattis said the United States remained fully engaged with its partners.
"Like it or not, we are a part of the world," he said. "What a crummy world if we all retreat inside our borders."
Nevertheless, reversing or slowing North Korea's nuclear and missile programs has become a security priority for Washington, given Pyongyang's vow to develop a nuclear-tipped missile capable of hitting the U.S. mainland.
The Trump administration has been pressing China aggressively to rein in its reclusive neighbor, warning all options are on the table if North Korea persists with its weapons programs.
"The Trump administration is encouraged by China's renewed commitment to work with the international community toward denuclearisation," Mattis said.
"Ultimately, we believe China will come to recognize North Korea as a strategic liability, not an asset."
However, Mattis said seeking China's cooperation on North Korea did not mean Washington would not challenge Beijing's activities in the South China Sea.
The U.N. Security Council on Friday expanded targeted sanctions against North Korea after its repeated missile tests, adopting the first such resolution agreed by the United States and China since Trump took office.
In another sign of increased pressure on North Korea, Japan's navy and air force began a three-day military exercise with two U.S. aircraft carriers in the Sea of Japan on Thursday.
Japanese Defence Minister Tomomi Inada, speaking at the Singapore forum, said Tokyo backed the United States using any option to deal with North Korea, including military strikes and was seeking a deeper alliance with Washington.
But she also said she was concerned about the situation in the South China Sea and in the East China Sea.
China's claims in the South China Sea, through which about $5 trillion in ship-borne trade passes each year, are contested by Brunei, Malaysia, the Philippines, Taiwan and Vietnam. China and Japan both claim islands in the East China Sea.
