Singapore's prime minister says the trade dispute between America and China is the most urgent issue in Southeast Asia.
Singapore Prime Minister Lee Hsien Loong made the remarks at the end of the ASEAN Summit in Singapore.
"We are deeply concerned by the rising wave of protectionism and anti-globalization sentiment," he said.
Donald Trump's government threatened to impose tariffs on imports of products from China, saying they caused the burden on American producers who had to compete with their cheap prices. Beijing has responded with the threat of raising tariffs on US imports.
Other issues addressed at the summit include terrorism, technological sabotage, ISIS terrorist groups, warm South Korea and North relations, and human rights issues in Myanmar, where Rohingya ethnic people have flooded and fled to Bangladesh to escape violence.
