ATHENS — Greece on Tuesday signed a major privatization deal that will fulfill a key condition for the release of further bailout funding, but it will also displace thousands of refugees.

The deal, for a huge luxury real estate project on the site of the capital’s former international airport, was made in a memorandum of understanding between the state privatization agency, Taiped, and a consortium of Greek, Arab and Chinese companies. The land sits on a prime piece of coastline in Elliniko in southern Athens.

Elliniko is part of an ambitious privatization program by Greece’s leftist-led government and the country’s international creditors. Apart from Greece’s power board and other state companies, the portfolio of Greek assets for sale includes former government buildings, beaches and hotels.

The deal, which was frozen for a year and a half because of protests, was hailed as a breakthrough. Taiped’s chairman, Stergios Pitsiorlas, said the site, which covers four square kilometers, or 1.5 square miles, would accommodate “the largest urban regeneration project in Europe,” and create thousands of jobs for the debt-ridden nation. The site will also have the largest metropolitan park in Europe, he said. The office of Prime Minister Alexis Tsipras said the investment would help “restart the economy.”
