HONG KONG, Feb 23 (Reuters) - Hong Kong stocks jumped on Monday, led by tech and mainland shares listed in the city, as China is set to receive lower tariffs after the U.S. Supreme Court ruling.
By the noon trading break, the benchmark Hang Seng Index .HSI advanced 2.3% to 27,019.21, the strongest level since Feb 12.
The Hang Seng China Enterprises Index .HSCE which tracks major mainland firms listed in the city, bounced 2.5%, on track for its best single-day gain in a month.
Sentiment was largely upbeat following the U.S. Supreme Court's decision on Friday to strike down Donald Trump's sweeping tariffs, which China is making "full assessment" of.
China should see the largest tariff reduction as it faces the highest tariff rates at the outset, declining to 24% from 32%, according to analysts at Morgan Stanley.
U.S. President Donald Trump will travel to China from March 31 to April 2 for a highly anticipated meeting between the leaders of the world's two biggest economies.
"The U.S. tariff ruling and Trump's finalized China visit schedule is lending a support to risk appetite," Zhang Qiyao, chief strategy analyst at Industrial Securities, wrote in a note.
"Although Trump may seek other tariff tools as substitutes which could still bring some uncertainty, the risk of sharp twists in U.S.-China relations will be relatively controllable in near term ahead of his visit," he added.
The Hang Seng Tech Index .HSTECH rallied as much as 4% to rebound from a seven-month low struck in the Friday trading session amid renewed optimism towards China's AI developments.
Alibaba 9988.HK jumped 3.6% and Tencent 0700.HK rallied 3.3%. Chipmaker SMIC 0981.HK surged 4.6%, the best gain in nearly two months.
Investors are also digesting early data releases for the Chinese New Year holiday period, which delivered a "broadly firm" demand signal, with upbeat retail sales, resilient travel and improved home sales, according to Citi analysts.
"With the economy off to a steady start, market focus will shift to the NPC starting March 5th," they wrote in a note.
Around the region, MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS was up 1% in light trade.
