Prime Minister Stephen Harper's Asian adventure will take on a decidedly military air starting Sunday, a change from the focus on diplomacy and human rights during his four-day visit to mainland China.

The prime minister is scheduled to take part in a ceremony at Sai Wan War Cemetery in Hong Kong, where 283 Canadian soldiers lay buried.

On Monday he'll visit demilitarized zone between the two Koreas, making a visit to the Bridge of No Return.

The ominous name came about because prisoners of war who voluntarily chose to go to North Korea instead of staying in the South would be unable to return.

Harper is also scheduled to lay a wreath at the Seoul National Cemetery to honour Canadians killed during the Korean war.

Squeezed in between the two events, Harper will deliver a speech to the South Korean national assembly, the first Canadian prime minister to do so.
