TOKYO -- Japanese Prime Minister Shigeru Ishiba asked US President Joe Biden to address "strong concerns" in both Japanese and US business circles following Biden's order to block Nippon Steel's takeover of US Steel, local media reported Monday.

The prime minister conveyed the request during an online meeting with Biden, according to Jiji Press' report.

"Strong concerns are being raised not only in Japan but also in the US business community. I strongly urged that these concerns be dispelled," Ishiba told reporters, but he did not disclose Biden's response.

On Jan 3, the US president decided to block the takeover of US Steel by Japan's Nippon Steel, citing risks to national security, while urging the two steelmakers to "fully and permanently" abandon their plan.

On Saturday, Nippon Steel and US Steel said the Biden administration delayed until June an order for the Japanese company to abandon its $14.1 billion bid for US Steel.
