Poland signs agreement with France's DCNS to work on building submarines

Poland's state-run defence firm PGZ has signed a memorandum of understanding with French military shipbuilder DCNS that could allow them to work together on building submarines in Poland, PGZ said in a statement. The agreement marks an improvement in relations between Poland and France after Warsaw last year cancelled a preliminary $3.4 billion (2.7 billion pounds) helicopter deal with France's Airbus, a decision which has angered Paris.
