Taiwan claims it has discovered the remains of what seems to be a Chinese weather balloon that dropped.
Taiwan’s military said it had spotted an unidentified object drifting above Dongyin – a Taiwanese-controlled island off China’s coast – at 11:00 local time (03:00 GMT) on Thursday.
It later found a crash site on a shooting range.
Initial investigations suggested the remnants were part of a meteorological instrument, the military added.
On Friday, Taiwan’s Defence Minister Chiu Kuo-cheng said that officials would further investigate the crashed balloon but would not “jump to conclusions”.
This is the first time such a discovery has been made in Taiwan’s offshore islands, said senior defence official Chen Yu-lin, according to local media.
Tensions between China and the US have seen a fresh spike in recent weeks, after the US downed what it said was a Chinese surveillance balloon in its airspace earlier this month. The US also shot down three other objects it says are unlikely to be foreign spy crafts.
The sphere found on Dongyin was about a metre in diameter and bore the name of a China-based company that, based on online searches, stocks meteorological and radio appliances.
The company Taiyuan Radio No 1 Factory Co. Ltd is based in Taiyuan, one of China’s main industrial bases and capital of Shanxi province.
The sphere was also marked “GTS13 digital atmospheric sounding instrument” and “meteorological instrument”, with simplified Chinese language characters, the military said in a statement.
China has used simplified Chinese characters since the 1950s, but Taiwan continues to use traditional characters.
Authorities have not released pictures of the object.
Taiwan’s defence ministry said on Tuesday that it has not spotted any surveillance balloons from China in its vicinity, but also said it will shoot down any balloon it deems a threat.
China sees self-ruled Taiwan as a breakaway province that will eventually be under Beijing’s control.
But Taiwan sees itself as distinct from the Chinese mainland, with its own constitution and democratically-elected leaders.
