Asian markets traded mostly lower in early deals today, as the investor sentiments dulled after US President-elect Donald Trump announced plans to impose an additional 10% tariff from China and a 25% tariff on imports from Mexico as well as Canada. Participants keenly awaited for release of key US economic data and the Bank of Korea's upcoming interest rate decision later this week. Japan’s Nikkei plunged after two straight day gains amidst woes over global trade tensions. Moreover, stronger local currency yen also pressured the index further.
