China poses a challenge to NATO's values and interests and the alliance has to take into account the consequences for its security from China's investment in modern long-range weapons, NATO Secretary-General Jens Stoltenberg said on Wednesday.
Speaking at the start of the second day of a NATO summit in Madrid, he also said he expected "a very important decision" concerning challenges faced by the alliance on its southern flank and on terrorism.
