TAIPEI (Reuters) -Taiwan will "handle" Chinese balloons flying nearby based on threat assessments, though officials believe the current wave is for weather purposes, driven by the prevailing winds at this time of year, the defence ministry in Taipei said on Wednesday. The potential for China to use balloons for spying became a global issue in February when the United States shot down what it said was a Chinese surveillance balloon. China said the balloon was a civilian craft that accidentally drifted astray.
