A weeklong strike by thousands of truckers in South Korea has triggered major disruptions in cargo transport and production that have caused 1.6 trillion won ($1.2 billion) in damages, officials said Monday.

An extended strike may eventually worsen the global supply chains already battered by Russia’s invasion of Ukraine and China’s pandemic curbs. But the strike’s impact has so far been largely limited to South Korea’s domestic industry. The world’s 10th largest economy, the country hasn’t reported any major disruption of exports of key items like semiconductors.

The fourth round of negotiations between the striking truckers and government officials Sunday failed to reach a deal. Transport Ministry officials said they would seek to continue talks to end the strike, but the Cargo Truckers Solidarity said Monday it has no immediate plans to resume the negotiations.
