Polish Defence Minister, Mariusz Błaszczak, has attended a military training of U.S. and Polish soldiers in the northwest of Poland, ahead of the planned visit of the United States Secretary of State, Mike Pompeo. The latter is expected to visit Warsaw on Saturday (August 15) to sign a defence cooperation deal with Poland. On Wednesday, however, Pompeo visited Prague where he met with Czech Prime Minister Andrej Babis and and Czech President Milos Zeman.
