BEIJING, March 19 — China has not yet found any sign a missing Malaysian Airlines jet entered in its territory, Foreign Ministry spokesman Hong Lei said on Wednesday.

Hong made the comments at a daily news briefing.

Investigations into the mystery of the missing Malaysian aircraft appeared to be at a deadlock, with no conclusive evidence yet of foul play and doubts surfacing about whether nations would share military tracking data that could show where the plane may have headed. — Reuters
