The Shopify Fulfillment Network would be good if you're doing higher volume, but for lower volume you might consider using Amazon FBA. It's a pretty smooth setup and can be automated.
Here's the set up I use: https://speedboostr.com/automate-order-fulfillment-on-shopify
Example use case: for USA orders on Shopify we have it set to fulfill by Amazon automatically. For international orders, if it's in an international market where we sell on Amazon, we fulfill from that location, otherwise we fulfill manually.
Depending on the time and overhead you want to invest, you could technically send in inventory to Amazon centers around the world and fulfill from them by region. And then also have your products listed in that market. It can become a pain dealing with the different VAT / tax nexuses, listing creation / management, but if you have the capital you can also scale it quite well.
Here's the Shopify fulfillment network link if you want to check that out: https://www.shopify.com/fulfillment. Might be good if you get your order volume up (I think they said 10+ orders per day for it to be worth the ROI).
Either way, I think shipping in bulk from China to North America and Europe, then dispatching from there would be your best bet if those are where most of your customers are going to be coming from.
