BRUSSELS, July 10 (Xinhua) -- NATO Secretary General Jens Stoltenberg on Tuesday said that defense spending and burden-sharing will be high on the agenda of the upcoming NATO summit.

The leaders of 29 NATO Allies and many partner nations will meet in Brussels on Wednesday and Thursday for a summit at the NATO's new headquarters.

"They will take decisions to strengthen NATO's deterrence and defense, step up in the fight against terrorism, and achieve fairer burden-sharing," Stoltenberg told reporters ahead of the summit.

During the meetings, Allies will also address key security challenges with leaders from Finland and Sweden, as well as the Presidents of the European Council and the European Commission. Enditem
