Maybe, but there's 5000 years of hatred between China and Japan. Japan might get pissed at us, but they aren't stupid.
Japan may not be...they only have one friend on the Pacific Rim...the country that nuked them.
But China would be happy to show that the United States is "racist" against Asians....sound like a familiar theme in the media recently....to weaken pro-US/anti-China feelings in SE Asia. China may not have ordered Biden to sit out the meet-and-greet with Japan's PM, but they won't turn away a free gift, either.
"The US is so racist they freely insult their favorite lap-dogs of Japan. What do you people in Thailand (or Philipines, or what ever) think the Americans say about you behind closed doors?"
