Before we head into Donald Trump’s first full day in office on Tuesday, here’s a look at what his first day back as president meant for technology, climate and markets

TikTok is receiving surprising support from unlikely quarters, but it remains unclear whether the app will remain online in the United States come Sunday

The short video app is facing a January 19 deadline for a ban in the US, unless its Chinese owner ByteDance divests its US operations

The US President-elect says a pause would give his administration time to pursue a "political resolution" to the issue

“The only way to beat China is to stay ahead of them," US Commerce Secretary Gina Raimondo said in an interview

An intelligence firm claims a Chinese state-linked operation, dubbed ‘Spamouflage’ or ‘Dragonbridge’, is pushing spam and targeted messages onto the net

In a 99-page document submitted to a US court, TikTok and ByteDance argued the divest-or-ban bill was punitive, speculative and needed to be struck down

Trump’s remarks are a sharp U-turn from his earlier stance on the app, given it was he who began the US crusade against TikTok during his presidency in 2020

Analysts say tariffs target sectors where the economic impact will be limited and where Chinese companies' dominance appears unassailable

The President said migration was good for the US economy, which is a global outlier with a positive growth forecast for 2024

The superpower leaders last exchanged words at an historic summit in November with Beijing describing it as a “candid and in-depth exchange”

The US Justice Department also said the bill forcing ByteDance to divest TikTok would put the government in a stronger legal position than if the app was simply banned
