Even if you get your device back, after someone takes it behind the curtain and fiddles with it ... How can you be sure that they have not compromised it for its onward journey?
For most of us here in particular that's very silly as well as completely unrealistic, we need some level of electronics for our work even beyond that it makes many kinds of travel much more practical. However, what is worth considering (at least when traveling internationally) is to have specific dedicated travel electronics. One consequence of the end of Moore's Law and the flattening of the performance curves in PCs and now mobile devices as well is that older kit can still be perfectly serviceable for travel usage. I replaced my 4 year old notebook and 3 year old phone last year for example, but this time rather then sell the old ones (which aren't worth that much anyway) I just kept them and changed them into specific clean travel devices (and with the notebook in particular oriented around remote work for most stuff).
That kind of opsec was a lot more expensive and difficult at one point, but these days I think it's ever more practical and it reduces potential headaches and opportunities for screwups (by me) a lot. It's much easier to make sure nothing critical is on a device I wipe regularly and much easier to maintain compartmentalization with physical separation. If any of it ever was seized I'd still be bummed/irritated, it's still worth some money and on a practical level it'd mean I didn't have it for the rest of the trip (even if the rest is just "the flight home" and all I wanted was to read a bit). But nothing I couldn't just write off ever seeing again or that could cause me any trouble even if it was cracked.
Furthermore if a laptop (or other electronic device) is purchased in a foreign country either dont bring it back or bring it back and shred it.
I know this sounds extreme and expensive, but with cloud storage and cheap laptop's i cant imagine anyone travling to a foreign country not being able to have a secondary "disposable" machine with cloud backups (could be a challenge in say china, but if you are doing buisness in a country like that (government monitored and access restricted) you should have company policies in place already).
As recommended elsewhere in these comments, I'll likely use Chromebook + https://www.paperspace.com/ in the future, and implement a travel policy for my team regarding what material can be taken where.
