Just looking at the list of the 26 leaders of the countries participating in the parade, the collective absence of Western countries, Serbia and Slovakia are the only countries in Europe to attend. On the Asian side, Thailand, Singapore, India did not come.
Such major occasions, to a certain extent, can see the relationship between countries, but not completely, some countries will be subjected to various pressures, choosing to send a second hand or other political want to attend.
But countries like Japan and the Philippines will definitely boycott our event. Don't pay attention to these people.
