Washington— Facebook and Twitter have not detected Chinese meddling in the 2018 elections, company officials said, casting doubt on claims by US  President Donald Trump that the Asian nation is trying to interfere.

The social media giants have reported online disinformation campaigns ahead of the November 6 elections that appear to originate from Russia and Iran. But media representatives for both companies, who spoke on condition they not be identified by name, said they haven’t found evidence so far of such activity from China.

Facebook and Twitter are the latest in a string of tech companies that have made findings undercutting Trump’s claim. Last week, top cybersecurity firms — FireEye, Symantec and Crowdstrike — said that, in working to help safeguard the November elections, they haven’t seen evidence of digital interference by China.

In the wake of Russian interference in the 2016 election, Facebook and Twitter have stepped up efforts to detect and stop foreign-government disinformation campaigns on their platforms. The companies use automated algorithms and human reviews of suspicious activity to search for co-ordinated campaigns.

Facebook and Twitter have both suspended or removed accounts that appeared to emanate from Russia and Iran and seemed to be intended to influence US opinion as November's elections approach. It is possible that Chinese activity could be undetected or surface closer to the election.

The Trump administration’s claims about Chinese interference have mounted since September, when Trump told the UN Security Council that “China has been attempting to interfere in our upcoming 2018 election, coming up in November, against my administration”.

Vice-president Mike Pence followed up with a speech earlier in October, saying: ‘There can be no doubt: China is meddling in America’s democracy.’ Pence characterised Beijing’s behaviour as “an unprecedented effort to influence American public opinion, the 2018 elections, and the environment leading into the 2020 presidential elections”.

Trump and Pence have both cited a paid advertising supplement the Chinese government placed in Iowa''s Des Moines Register newspaper criticising the administration’s trade policies.

Beijing and Washington are currently locked in an escalating trade conflict, and late in September, US and Chinese warships nearly collided in the South China Sea, where both nations are seeking to assert their regional dominance.

The department of homeland security, Federal Bureau of Investigation and office of the director of national intelligence warned last Friday that nations including China were engaged in “ongoing campaigns” to “undermine confidence” and influence policy and opinion in the US

The administration has not provided evidence to back up the allegations.
