Denmark, Poland celebrate 100 years of diplomatic ties

WARSAW, Poland (AP) - Danish Crown Prince Frederik and Crown Princess Mary marked 100 years of Denmark's diplomatic ties with Poland with a one-day visit to Warsaw Monday that involved meeting Poland's president and World War II veterans.

Frederik and Mary were greeted with military honors by Polish President Andrzej Duda in front of the Presidential Palace.

Later in the day, they were set to open a conference at Warsaw University on the history of the countries' ties.

They were also due at the nearby Polish Academy of Sciences to dedicate a memorial plaque to Danish 19th-century sculptor Bertel Thorvaldsen, who made a popular monument in Warsaw to Polish astronomer Nicolaus Copernicus.

They were also to lay a wreath at the Tomb of the Unknown Soldier and meet war veterans.

Talks in coal-reliant Poland were to include climate protection and a joint gas pipeline project, Baltic Pipe, to bring Norwegian gas to Denmark and Poland.
