"Russia must take into account that the US, or the West in general, can make a decision to arm Ukraine and that it is a card that is held by the West, that can be used in the future, if not today," The Financial Times quoted Tomasz Siemoniak as saying. "The Polish position is that we should not say that this card will never be played."
Siemoniak added that Poland is "not afraid of cooperation" with Ukraine.
In late January, Polish Foreign Minister Grzegorz Schetyna said, "Poland is open to arms sales to Ukraine."
While the US Congress is actively promoting the idea, a number of EU states, including Germany, the United Kingdom, France, Italy, Netherlands and Spain, reject the initiative.
Russia has repeatedly urged parties to the conflict in Ukraine to seek a peaceful solution to the crisis and warned that arming Ukraine would only aggravate the situation.
