HONG KONG, April 11(Reuters) - Hong Kong and China stocks reversed earlier declines on Friday and narrowed the week's losses, as a chip share rally and potential state buying shielded against more losses from the escalating trade war with the U.S.
The Hang Seng Index .HSI jumped 1.1% at the close, reversing an earlier fall of as much as 1.2% in morning trades. The tech subindex .HSTECH climbed 1.8%.
Chipmakers were among the biggest winners, with Hua Hong Semiconductor 1347.HK rallying a shade over 20% before ending the day with a 14% gain. Peer SMIC 0981.HK climbed 6%.
On the mainland, the Shanghai Composite Index .SSEC and the blue-chip CSI 300 Index .CSI300 also reversed losses to climb 0.5% and 0.4% respectively.
The CSI Semiconductor Industry Index .CSI931865 led gains onshore with a jump of 2.7%.
The gains in the afternoon session have helped both Hong Kong and mainland markets to recover some ground from a heavy selloff earlier in the week as the trade war between the world's two largest economies heated up.
U.S. President Trump paused most of his "reciprocal" tariffs on Wednesday, though he has singled out China with eye-popping duties of 145% on its goods.
Despite the gains on Friday, the Hang Seng Index .HSI still suffered a weekly loss of 8.5%, the biggest since February 2018, while the CSI 300 Index .CSI300 posted the biggest weekly retreat in four months.
Hong Kong's bounce was following a move in mainland A shares that was widely believed to involve buying by Chinese state funds known as the "national team", according to Steven Leung, director of institutional sales at UOB Kay Hian in Hong Kong.
Beijing stepped up efforts to stabilise mainland markets this week, with a state fund and state holding companies stepping into the market to buy stocks. A slew of listed firms have also announced share buybacks.
Beijing on Friday also increased its tariffs on U.S. imports to 125%, hitting back against Trump's decision to hike duties on Chinese goods to 145%, raising the stakes in a trade war that threatens to up-end global supply chains.
Liam Zhou, founder of Shanghai-based Minority Asset Management, said his $1 billion portfolio is now fully invested in China stocks and he was wagering on the country's economic resilience.
"China's retaliation against U.S. tariffs drew strength from the fact that China has reduced economic reliance on the U.S., it has proactively tamed property sector risks, made technology breakthroughs and is upgrading the manufacturing sector," he said.
Elsewhere, MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS also reversed earlier declines to trade 1.3% higher, while Japan's Nikkei .N225 narrowed losses to less than 3%.
