North&nbsp;Korea&nbsp;appears to be expanding work at its nuclear test site to include a second tunnel, a U.S.-based think tank said on Thursday, as South&nbsp;Korean and U.S. officials say&nbsp;North&nbsp;Korea&nbsp;might conduct a nuclear test any day.

Preparation work at the Punggye-ri Nuclear Test Facility's Tunnel No. 3 was apparently complete and ready for a possible nuclear test, the Center for Strategic and International Studies said in a report, citing commercial satellite imagery.

North&nbsp;Korea&nbsp;conducted six underground nuclear tests at the site from 2006 to 2017.

The research group said that for the first time, analysts spotted new construction activity at the facility's Tunnel No. 4, "strongly suggesting an effort to re-enable it for potential future testing".

Outside Tunnel No. 3, images showed a retaining wall and some minor landscaping with small trees or bushes, likely in anticipation of a visit by senior officials, it said.

The two tunnels were never previously used for nuclear tests and their entrances were demolished in 2018, when&nbsp;North&nbsp;Korea&nbsp;declared a self-imposed moratorium on testing nuclear weapons and its intercontinental ballistic missiles (ICBMs).

Leader Kim Jong Un has said he is no longer bound by that moratorium because of a lack of reciprocal steps by the United States during denuclearisation talks, and&nbsp;North&nbsp;Korea&nbsp;resumed testing ICBMs this year.

South&nbsp;Korean officials said this week that&nbsp;North&nbsp;Korea&nbsp;was poised to conduct a nuclear test "at any time" and that the timing would be decided by Kim.

South&nbsp;Korea's defence ministry spokesman, when asked about the report, said it was closely monitoring developments on&nbsp;North&nbsp;Korea's nuclear activity together with U.S. intelligence authorities but declined to make any further comment.

South&nbsp;Korean Foreign Minister Park Jin said on Monday after talks with U.S. Secretary of State Antony Blinken in Washington that any provocation by&nbsp;North&nbsp;Korea, including a nuclear test, would be met with a united, firm response.

He urged China, for years&nbsp;North&nbsp;Korea's only major ally, to use its influence.

Park also vowed to work to normalise an intelligence sharing pact with Japan "as soon as possible" to boost their responses to&nbsp;North&nbsp;Korea's nuclear and missile threats.

The accord, the General Security of Military Information Agreement (GSOMIA), had been a backbone of trilateral security information sharing by South&nbsp;Korea, the United States and Japan.

But South&nbsp;Korea&nbsp;had considered scrapping the pact with Japan in late 2019, during a period of strained ties, before a last-minute decision https://www.reuters.com/article/us-southkorea-japan-idUSKBN1XW087 to renew it in the face of U.S. pressure.

South&nbsp;Korean officials have said that since then, intelligence sharing with Japan had not been as smooth as it was before.
