Japan shouldn't ignore the data security risks posed by the Chinese video app TikTok, a senior ruling party official said. "Not only President Trump but also other countries such as the U.K. and India, are gradually becoming aware of the risks," Akira Amari, the ruling Liberal Democratic Party's tax panel chief, said Sunday on Fuji Television Network. "Since there are so many countries pointing out the risks, Japan cannot just stand by and watch." U.S. President Donald Trump on Friday ordered ByteDance Ltd., TikTok's Chinese owner, to sell its U.S. assets. Trump cited national security grounds, delivering the latest salvo in his standoff with Beijing.
