GERMAN FUNDING: Minister for Trade and Industry Panagis Papaligouras said yesterday that following talks with the German government, Bonn appears willing to fund projects of major importance for Greece with long-term credits for a period of time. Among these projects are a new power station at Ptolemaida with a capacity of 100,000 kilowatts, and a nitrogen plant. Papaligouras also said that a Greek factory had orders for German defense supplies valued at about 90 million marks (20 million dollars). There is to be an official announcement of this agreement after it has been signed. GREEK EMIGRANTS: An agreement was signed yesterday with Belgium on the issue of emigrant coal miners. The agreement is soon to be ratified. According to an announcement by the labor minister, the accord guarantees the status of Greek workers and their families who go to Belgium to work in mines and extends protection to them. Greek miners also acquire the right to exercise any profession they wish in Belgium after five years in the mines. Another contract to be signed shortly concerns social security for the miners and their families.
