BERLIN (AP) — President Barack Obama is joining the leaders of key European countries in Germany to discuss an array of security and economic challenges facing the trans-Atlantic partners as the U.S. prepares for President-elect Donald Trump to take office in January.

Obama's meeting today with the leaders of Germany, Britain, France, Italy and Spain is likely his last in such a setting before he leaves office. The session expands on lengthy talks he held the day before with German Chancellor Angela Merkel.

Since Obama's arrival in Germany, he and Merkel have focused on globalization and trans-Atlantic cooperation. The talks come largely in the context of what Trump's election means for efforts to seek peace in Ukraine and Syria, the NATO alliance, trade agreements and efforts to fight climate change.
