Polish foreign ministry spokesman Łukasz Jasina told reporters on Sunday that Rau was flying to South Korea to "strengthen the partnership" between Warsaw and Seoul in areas including defence and energy.
Polish Deputy Prime Minister and Defence Minister Mariusz Błaszczak said in an interview last week that Warsaw and Seoul had agreed to create a "consortium of arms makers" to manufacture weapons together for other countries.
A Polish deputy prime minister said last Tuesday that South Korea would help bring “cheap and safe" nuclear energy to his country as two Polish firms teamed up to build a nuclear power plant together with a South Korean partner.
The Polish foreign ministry said in a statement on Friday that during his trip to Seoul, Rau would meet with South Korean Unification Minister Kwon Young-se.
While in South Korea, Rau will also visit the demilitarized zone between the Koreas, the statement said.
While in Hanoi, Rau will meet with his Vietnamese counterpart Bui Thanh Son and attend a ceremony during which the Polish foreign ministry's Diplomatic Academy will sign a cooperation agreement with the Diplomatic Academy of Vietnam, according to the statement.
On the sidelines of his visit to Hanoi, Poland's top diplomat will meet with "members of the Poland-Vietnam Friendship Parliamentary Group at the National Assembly," the Polish foreign ministry said.
