Without trade shows or overseas business trips, is there a way to develop new overseas customers?

Yes, but the prerequisite is that you have a digital mechanism to let unfamiliar buyers discover you proactively. Trade shows are a channel for building trust face-to-face, but they are not the only option—nor should they be. The article mentions that younger buyers are seeking suppliers on LinkedIn and even TikTok, and digital communication is now mainstream. Practical directions you can work on include: building a multilingual website so search engines can find you, clearly explaining on LinkedIn what problems you solve, and using multilingual product catalogs so unfamiliar buyers can self-serve to understand your specifications and terms. The key is not which platform you use, but whether you have a narrative and content framework that allows buyers to understand your value before contacting you. Without this mechanism, business cards collected at trade shows rarely convert into sustained customer relationships.
