Why does Donald Trump see China as a threat on AI, but not on TikTok?

“This is money that normally would have gone to China,” Trump proclaimed on Tuesday while unveiling Stargate, an artificial intelligence project that will cost $500 billion, according to its participants OpenAI, Softbank, Oracle and MGX. It was another indication that keeping ahead of Beijing on AI is a priority of the Trump administration. But in his bid to save TikTok, the video app that was briefly banned in the US under a law that came into effect the day before Trump entered office, the president appears much more relaxed about China.
