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 defense 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.

Taiwan is on high alert for Chinese activities, both military and political, ahead of Jan. 13 presidential and parliamentary elections. Taipei has warned that Beijing may try to interfere to get voters to pick candidates China may prefer.
