House Speaker Mike Johnson (R-La.) and President Trump appeared to take different stances Monday on China's artificial intelligence developments. Why it matters: Interest in Chinese company DeepSeek's rapid advancements in AI sent U.S. tech stocks tumbling on Monday, as the mobile app climbed to no.1 on Apple's rankings of free iPhone apps.

Donald Trump has called China's DeepSeek AI a "wake up call" for US tech firms, following a significant decline in tech stocks and rising competition.

MIAMI: US President Donald Trump said on Monday (Jan 27) the low-cost Chinese AI model DeepSeek was a "wake up call" for US firms, after its emergence caused a rout in tech shares.
