Why?

As a general rule, UA simply is not interested in selling discount seats 6+ months ahead of departure. There's always time to offer a sale later, but if they start out with a low price and then demand comes in hotter than expected, they can't recoup that revenue.

If you know a market well, you can sometimes find a good deal well in advance, generally as a consequence of something else UA is doing. Otherwise, just monitor things and see how they look.

There are only two cases when it would make even the slightest bit of sense to book months in advance: (a) if upgrade space is available or (b) if a saver award is available. Outside of those two reasons, or maybe holiday travel, I don't even start looking for flights until ~3 months prior to departure for international and ~6 weeks prior for domestic. I do keep an eye on the Premium Fare Deals forum, though.

It depends upon how far you remember, I guess. 🤷‍♂️ 60K round trip sounds like a value from the early 90s, maybe? 60K each way is more recent, but depending upon the part of Asia you're talking about, the last chart went from ~70K to ~110K each way.
