Polish Minister of Defense Tomasz Siemoniak has stated that Poland will not supply Ukraine with heavy weaponry as the conflict with pro-Russian separatists continues.

''There is no chance of Poland sending heavy weaponry, Grom missiles, tanks or similar weapons,'' Siemoniak told the Gazeta Wyborcza daily.

While arguing that he sees no impediments to the prospective cooperation between the Polish and Ukrainian defense industries, he referred to German Chancellor Angela Merkel's reservations about arming Ukraine.

''Chancellor Merkel has argued that the decision to supply weapons to Ukraine does not frighten President Vladimir Putin, because it will be difficult for Ukraine to achieve a level that is comparable to the Russian military, and it will only further exacerbate the situation,'' he said.

Nevertheless, Siemoniak acknowledged that President of Lithuania Toomas Ilves has argued that Ukraine continues to fight with some weaponry from the 1960s and 1970s, while facing 21 century equivalents.

To date, Poland has supplied the Ukrainian armed forces with rations, blankets and other materials.

Siemoniak said that above all, Poland supports the implementation of a ceasefire.
