Crypto currency is also among those better tools. Government would be better served getting the hang of what it offers before its left behind.
How would crypto currencies better protect US companies from a foreign government placing large orders at US companies and then not paying? It is a standard practice to not pay for goods ordered until delivery (or sometime thereafter) when dealing on a B2B basis.
All a crypto currency would do is provide another payment method when the foreign government does decide to pay (and is not engaging in a trade war)
