Thailand and Cambodia signed a landmark peace agreement on Sunday in the presence of U.S. President Donald Trump, marking a major step toward resolving recent border tensions. Trump, who also signed the document as a witness, was joined by Malaysian Prime Minister Anwar Ibrahim at the ceremony. The signing kicked off Trump’s multi-nation Asia tour, which includes visits to Malaysia, Japan, and South Korea. The trip’s most anticipated moment will be his meeting with Chinese President Xi Jinping, where discussions are expected to focus on ending the U.S.-China trade war. Trump also hinted at a possible meeting with North Korean leader Kim Jong Un — their first since 2019. In Japan, he will meet new Prime Minister Sanae Takaichi before heading to Busan for the APEC summit and talks with South Korean President Lee Jae-myung.
