Polish copper firm KGHM should keep its foreign assets – minister

Poland's KGHM, which is one of the world's biggest copper producers, should not sell its foreign assets, Polish minister Henryk Kowalczyk said on Tuesday. The state-run and Poland-focused company invested overseas for the first time in 2011 when it bought Canada's Quadra FNX, for C$2.87-billion ($2.14-billion), the largest ever foreign acquisition by a Polish company.
