Hong Kong, Shanghai stocks sink as China hikes tariffs

Shares in Hong Kong sank Tuesday, in line with a sell-off across Asia and following a hammering on Wall Street as China's retaliation against US tariff hikes fanned fears of an all-out trade war between the economic titans.

The Hang Seng Index fell 1.50 percent, or 428.22 points, to 28,122.02.
