TCB is usually defined broadly to include all types of development assistance that positively affect a country's ability to secure benefits from international trade. Such assistance includes addressing the regulatory environment for business, trade, and investment, constraints such as low capacity for production and entrepreneurship and inadequate physical infrastructure, such as poor transport and storage facilities. USAID's TCB goal is to increase the number of developing countries that are harnessing global economic forces to accelerate growth and increase incomes.
