Contrary to what is stated in many comments here, there is no loan to Huawei. The loan is to the customers of Huawei, the telecom operators. Here is how it works: Huawei sells equipment to the telecom operator. The Chinese Development Bank pays Huawei. The telecom operator pays back the loan to the Chinese Development Bank over many years at very favorable conditions. Telecom operators absolutely love this setup as they can buy equipment without putting cash on the table. This is a huge competitive advantage for Huawei, and it explains why Huawei has grown to be the #2 telecom vendor in the world (behind Ericsson) in a matter of years. None of the western vendors (Ericsson, Alcatel-Lucent, Nokia Siemens Networks, Cisco) can give similar financing conditions to the operators, and this is going to very effectively kill the European and North-American competitors of Huawei.

I don't think this is correct. I work for a major telecoms equipment vendor. We definitely do sell into Cuba, and have billions of business in the US.
