China’s stock market rose across Asia on Tuesday as investors await more stimulus measures from the government to counter economic woes caused by COVID-19 restrictions, and shares of Taiwan’s TSMC rose after Berkshire Hathaway (NYSE:BRKb) disclosed its stake in the company.

China’s blue-chip Shanghai Shenzhen CSI 300 index jumped 1.7%, while the Shanghai Composite index gained 1.4%. Hong Kong’s Hang Seng Index continues to lead the way in Asia, jumping 3.3%, and is now close to confirming the bull market, up nearly 20% from a 13-year low reached in October.

The People’s Bank of China kept interest rates unchanged on Tuesday, but injected a significant amount of liquidity into the market as it struggles with slowing growth in the Chinese economy.

Weak industrial production and retail sales data released on Tuesday also boosted hopes that the government would deploy additional spending to support growth. Chinese stocks have rallied in recent sessions after the government eased some quarantine restrictions and travel rules as part of a tough “zero tolerance to the virus” policy.

But with the country now facing its worst outbreak in 6 months, the chances of further easing of restrictions seem unclear. But it could also spur the government to take more stimulus measures.

Shares of Taiwan Semiconductor Manufacturing Corp (TW:2330), also known as TSMC, rose more than 4% after Warren Buffett’s Berkshire Hathaway Inc (NYSE:BRKa) disclosed a stake of more than $4.1 billion in the world’s largest chip maker.

The stock, which is also the country’s largest, helped the Taiwanese index climb nearly 3%.

The move also benefited a broader range of technology stocks in Asian markets, with Hong Kong and South Korea’s indexes rising the most.

However, the rest of the Asian bourses saw mixed performance after somewhat hawkish signals from the US Federal Reserve. Fed deputy governor Lael Brainard said that while the central bank will consider less significant interest rate hikes in the coming months, it has no intention of suspending interest rate hikes.

Her comments indicated that the US interest rate is likely to continue to rise in the near term and exceed the levels seen during the 2008 financial crisis. This scenario is expected to continue to weigh on Asian stock indices.

Japan’s Nikkei 225 index was unchanged after data showed the world’s third-largest economy unexpectedly contracted in the third quarter, likely indicating increased pressure on local equities.

India’s Nifty 50 index fell 0.1 percent and South Korea’s KOSPI index rose 0.1 percent.
