Equities in Asia declined after a sell-off in technology shares spooked investors assessing threats to earnings growth for the industry that propelled last year’s rally. The yen slipped and 10-year U.S. yields consolidated below 2.8 percent.

Stocks retreated across the region, with Samsung Electronics Co. and Tencent Holdings Ltd. the biggest decliners on the MSCI Asia Pacific Index. Earlier, American tech shares suffered their worst drop since the broad market correction in early February as investors were rattled by news from Nvidia Corp. and mounting concerns surrounding Facebook Inc. The British pound rose following a report on plans to avoid a post-Brexit hard border with Ireland. The yen declined amid signs of an improving geopolitical situation with North Korea.

Concerns over trade tensions, sparked by President Donald Trump’s protectionist moves, have further stoked volatility that flared in early February amid high valuations and tighter liquidity. The Trump administration is mulling a crackdown on Chinese investments in technologies the U.S. considers sensitive, the latest step in his plan to punish China for violations of intellectual-property rights.

The geopolitical front at least has offered some solace, with China confirming Wednesday that North Korean leader Kim Jong Un met with President Xi Jinping on a surprise visit to Beijing — the latest in a series of diplomatic meetings pointing towards a reduction in tensions.

Meantime, Facebook Chief Executive Officer Mark Zuckerberg is expected to testify before the U.S. House Energy and Commerce Committee as lawmakers grow increasingly concerned about privacy protection. Another tech woe has been questions about the near-term prospects for self-driving vehicles in wake of a death in Arizona. Nvidia Corp., the graphics-chip maker, temporarily suspended its self-driving vehicle testing.

Elsewhere, oil extended a drop for a third day after declining on a report that American crude storage surged.
