Como dizer "Licitações Públicas" em inglês

Na minha opinião, as duas formas são corretas

Open tender:
A bidding process that is open to all qualified bidders and where the sealed bids are opened in public for scrutiny and are chosen on the basis of price and quality. Also called competitive tender or public tender.

Government procurement:
The act of obtaining goods or services for a public agency. Due to the impressive size of government related purchasing activity in the United States, which is often highly regulated, a substantial number of business operators find it profitable to cater almost exclusively to government procurement needs. Also called public procurement or public tendering.
