You're traveling to Asia, and I know I'm not alone on the forum at having never done that or shopped for an airline ticket to that region. The comments below come from a not-terribly-useful background.
After I bought it, the ticket for my 2018 trip to Europe bounced repeatedly between almost-$900 and almost-$1400.
If you have watched for quite some time as the fare hovered around $1700 and it has now spiked to over $2400, this may indicate that drops below the $1700 range are very unlikely. There is absolutely no guarantee that a fare will remain the same or even close to the same as you get closer to the departure date.
I also see that you are looking at an outbound non-stop on a route with a lot more connecting flights. Your choice is obviously going to be more popular than the ones involving connections. For European flights I've often observed a widening of the price gap between non-stop flights and connecting flights as the travel date approaches, so I think at this point you should consider the possibility that the fare may not ever come down. I'd be looking at connecting flights and deciding which one or two I liked best, just in case nothing good happens to the non-stop fare in the next two weeks or so.
