President Donald Trump praised China’s military parade in Beijing as “beautiful” but said the United States should have been acknowledged in President Xi Jinping’s speech, citing America’s support to China during World War II, according to Reuters.

The ceremony, marking 80 years since Japan’s defeat, drew global attention with Russian President Vladimir Putin and North Korea’s Kim Jong Un in attendance.

Afterward, Trump posted a sarcastic message suggesting Xi, Putin, and Kim were “plotting against the US,” a remark the Kremlin brushed off as irony, Reuters reported.
