Asian markets tank following Wall Street's loses: Nikkei down 300 points, Hang Seng loses 0.3%

Asian equities tumbled on Thursday, mirroring Wall Street's losses, fueled by US economic anxieties. Concerns over Donald Trump's proposed tax cuts and their potential impact on the US federal deficit intensified pressure on US Treasuries. A weak US government bond auction and Moody's credit outlook downgrade further dampened investor sentiment, halting a recent rally driven by easing China-US trade tensions.
