Mr Yi was seen leaving by car before the dinner began.
The dinner was also meant to be attended by US Secretary of State Anthony Blinken and Russian Foreign Minister Sergey Lavrov.
The news comes as tensions between the US and China near a breaking point following Nancy Pelosi’s visit to Taiwan.
It was reported earlier that Japanese Foreign Minister Yoshimasa Hayashi agreed with U.S. Secretary of State Antony Blinken to strongly condemn China’s ballistic missile launch on Thursday he was also scheduled to attend the ASEAN plus dinner.
The move can be seen as a snub to Russia as well. Sergey Lavrov, the Russian Foreign Minister, was also set to attend the dinner and was likely looking forward to having a de facto ally, China, in attendance.
