BEIJING (Reuters) - China on Thursday urged Japan to act cautiously after government and defence industry sources in Tokyo said U.S. and Japanese companies are collaborating on new missile defence radars.

As nuclear-armed Pyongyang builds ever more advanced missiles with the ability to strike anywhere in Japan, Tokyo is likely to fund a ground version of the ship-based Aegis defence system deployed on warships in the Sea of Japan, sources told Reuters.
