Canada blocking NATO pledge for more defence spending -sources

OTTAWA (Reuters) - NATO wants all 28 member states at a summit next week to commit to boost their defence spending, but Canada opposes the move, straining ties inside the alliance, two sources told Reuters on Thursday.

The sources, both familiar with negotiations on the issue, said NATO officials were pushing for a joint pledge to increase spending to two percent of gross domestic product within 10 years. The NATO summit will be held in Wales on Sept. 4-5.
