Pakistan's core interests should be protected and the NATO strike won't discourage Pakistani effort to work with international community fighting terrorists, the Pakistan Ambassador told China Daily on Monday.

NATO fighter jets and helicopters attacked two Pakistani border check posts in Mohmand tribal region near the Afghan border on Nov 26, killing 24 troops and injuring 13 others.

"This should not be the product of the alliance and cooperation between US and Pakistan," Masood Khan, the Pakistan Ambassador to China, said in an interview with China Daily in the Beijing-based embassy on Monday.

He demanded a complete investigation and the conclusion should be shared with Pakistan.
