The U.S. president's abrupt decision to cut back military drills with South Korea last week, which he described as hostile to Pyongyang, has reinforced fears that Trump's unpredictability could strain alliances that have long maintained peace in the region, government officials and security experts said, Reuters reports.
"The decision will certainly fuel growing doubts in the region about U.S. security commitments," said Jeremy Chan, a senior analyst with political risk consultancy Eurasia Group and former U.S. diplomat in Japan and China.
Adding to the anxiety, the United States cancelled another military exercise with South Korea scheduled for next month, Seoul said on Monday, after Washington cited constraints on U.S. forces due to the Iran war.
Trump has been frustrated by the failure of U.S. allies to support the war and made it clear that many of them must spend more on their own defence, a White House official said when asked about such concerns.
He is eager to restart talks with North Korea and secure a win on the international stage to counter his unpopular conflict with Iran, according to a person briefed on discussions between U.S. and South Korean officials.
Trump's push to meet Kim - which has so far drawn a frosty response from Pyongyang - could backfire and embolden nuclear-armed North Korea, said Itsunori Onodera, an influential Japanese lawmaker and former defence minister.
Such a prospect is "extremely troubling" for Tokyo, he said on a Fuji TV news programme last Thursday. Despite Trump's overtures, Pyongyang fired a volley of ballistic missiles off its east coast earlier that day, triggering alerts in neighbouring South Korea and Japan.
What worries Japanese officials more is Trump's approach as Tokyo embarks on talks with Washington over how much it should pay towards the cost of hosting U.S. forces, America's largest overseas deployment.
Japan is bracing for the possibility that Trump could, with little warning, demand a sharp hike that would be politically difficult to swallow, said a senior Japanese government official, requesting anonymity due to the sensitivity of the matter.
Trump could also wield upcoming U.S. military exercises with Japan in October as leverage, analysts say. Officials in Washington and Tokyo said they did not expect the exercises to be curtailed, though Trump could change his mind at any point, they cautioned.
Nowhere are concerns about China's growing military pressure more acute than in Taiwan.
Trump has held up approval of a $14 billion package of arms sales to Taipei in order to maintain warm relations and a fragile trade truce with China's Xi.
As Trump prepares for his latest round of summitry with Xi in Washington next month, officials in Taipei say they expect Washington will at the very least carve up the arms sales into smaller chunks to try and avoid upsetting Beijing too much.
Trump's latest actions have also rocked confidence in India, where the U.S. risks squandering years of efforts to draw New Delhi closer as a counterweight to Russia and China, security analysts say.
It also comes after the Pentagon's decision in June to rename its Asia military headquarters to Pacific Command from Indo-Pacific Command, a move some analysts say is a sign India is no longer as strategically important to Washington.
The Pentagon denied any such shift. But Trump's steep tariffs on Indian exports and repeated claims that he had mediated an India-Pakistan ceasefire had already exasperated New Delhi. Officials there are now "very, very cautious" about committing to long-term defence deals with Washington, according to two Indian sources with knowledge of the matter.
"The latest decision only reinforces President Trump's transactional view of foreign affairs and serves as a reminder that differences over specific policies, even among allies, can carry costs for the broader bilateral relationship," said Pearl Pandya, senior analyst at Armed Conflict Location & Event Data, a conflict monitoring group.
