TAIPEI (AFP) - Facebook vowed on Tuesday (Nov 5) to step up monitoring for any attempt to use its platform to meddle in Taiwan's elections as the island's authorities say they face growing interference from China.

Taiwan will elect a new president and Parliament on Jan 11, and relations with the mainland are dominating the campaign.

Beijing has ramped up Taiwan's isolation ever since President Tsai Ing-wen took office three years ago because her party refuses to acknowledge that Taiwan is part of "one China".

Ms Tsai is seeking a second term against Mr Han Kuo-yu, a challenger who favours much warmer ties with Beijing.

She and her party have accused Beijing of attempting to influence the elections by spreading disinformation via social media.

On Tuesday, Facebook said it would establish a regional election centre in Singapore in the final weeks before Taiwan's elections, following similar moves in the United States, India, Indonesia and the European Union.

"Protecting elections at the company is a major priority for us," Ms Kate Harbath, Facebook's public policy director and global elections lead, told reporters via a videoconference in Taipei.

"Now we are heavily focused on these upcoming elections in Taiwan," she added, as well as upcoming polls in countries including Sri Lanka and Singapore.

"Each election has different risks," she said, adding that the company starts a year before an election to assess what is involved.

Facebook said it currently has 40 teams that focus on elections, to increase transparency, reduce disinformation and harmful content, as well as removing inaccurate voting information or any content that violates community standards such as hate messages.

"Our product teams are building tooling to better monitor... in order for us to be able to take quicker action and we can respond to those things in real time," Ms Harbath said.

Faced with criticism that the site has been used to manipulate polls, Facebook has been under mounting pressure to improve how it spots meddling and misinformation, as well as to scrutinise political advertisements.

It will introduce strict criteria for political ads in Taiwan, requiring those who want to advertise about elections and politics to confirm their identity and location, and disclose who is responsible for the ad.

Facebook said it has also been working with third-party checkers, including an independent fact-checking organisation in Taiwan.

In a global initiative set to start mid-November, the social network will also step up a system that makes clear when information comes from state-controlled media outlets.

Facebook in August removed hundreds of fake accounts it said was involved in "coordinated inauthentic behaviour" focused on Hong Kong's ongoing protests.

Since the protests began, Beijing's well-oiled state media machinery has launched a global propaganda campaign both online and on social media.

Facebook said it has not detected such moves targeting the Taiwan elections so far.
