Beijing has staged multiple military drills around the island in recent years, drawing condemnation from the United States and its allies.
Before he announced his bid to run on Monday, Gou earlier this year sought the candidacy for the opposition KMT, which advocates for friendlier relations with Beijing.
The KMT has not disguised its anger at Gou's entry into the race for president, seeing his move as opening the way to a victory for the DPP's Lai by splitting the opposition vote.
Most recent polls put the DPP's Lai on around 35-40% of the vote, around 10 percentage points clear of his closest rival.
To qualify as an independent, he has to collect close to 300,000 voter signatures by Nov. 2, according to election regulations.
