There are competing international development models and worldviews, and technology is a key component in both. The American development model deploys technology to support developing nations’ self-determination and improve peoples’ lives. Competing development models use technology as a means of control, robbing nations of their sovereignty. Diplomatic engagement is vital to clarify the different development paths nations face — and to build lasting partnerships that improves lives, increases opportunity, and fosters freedom across the globe.
