Hong Kong stocks hit a three-month high amid expectations of improved Sino-US ties with mainland tech firms leading the charge.

The benchmark Hang Seng Index rose by 294 points or 1.4 percent to close at 20,891 points, a new high for this year and since early November last year. Turnover on the main board was HK$178.45 billion.

In the mainland, the Shanghai Stock Exchange Index rose 1.27 percent or 41 points to 3,270 points, while the Shenzhen Component Index jumped 2.26 percent or 229 points to 10,393 points.

The rallies came after the US Postal Service made an abrupt U-turn last night to resume accepting international inbound shipments from China and Hong Kong - less than 24 hours after announcing a suspension.
