The Ministry of Science and ICT announced Friday that the global body adopted South Korea’s artificial intelligence-assisted automobile security technology, smart grid technology, distributed ledger technology and two-way radio signal communication technology as global standards.

ITU made the decision in the meeting in Geneva, Switzerland. The meeting ended Thursday after opening Aug. 27.
