I was reading the news when I saw the sentence with 上で (see the sentence with highlight).
I was thinking if it should be read as うえ or じょう。I am inclined to read this as じょう because it doesn't fit into the expression うえで which shows that something happens after one thing, but at the same time, I am not 100% sure because I haven't seen じょう (which probably means "being of the type of" based on rikaikun add-on) in this context before.
Sure, I have seen じょう in contexts presented in here where it means "for the sake of, from the standpoint of" but I don't think the sentence in question falls under this category of じょう。
