SEOUL, Nov 4 — The powerful sister of North Korea’s leader is warning the United States that her country will mount a stronger response to Washington’s “invariable hostile policy” toward Pyongyang, the state news agency KCNA reported yesterday.

“In the present reality when new records are being set in the implementation of the US hostile policy toward the DPRK, it is natural that new records should be created in our reflective counteraction,” Kim Yo Jong was quoted as saying by KCNA, using the acronym for the Democratic People’s Republic of Korea.

The statement comes soon after Pyongyang blasted the FBI’s allegations it was behind the theft of $6 billion from cryptocurrency platform Binance, as it test-fired strategic cruise missiles in a new display of its weapons capabilities.
