Il Nuovo Postiglione - Unidentified gunmen attack China hotel in Afghan capital

Smoke could be seen pouring from the multi-storey Kabul Longan Hotel as Taliban security forces rushed to the site and sealed off the neighbourhood.

The Taliban claim to have improved security since storming back to power in August last year but there have been scores of bomb blasts and attacks, many claimed by the local chapter of the Islamic State group.

A Kabul police spokesman told reporters the attack was carried out by "mischievous elements".

"Security forces have reached the area and the clearance of the raiders is underway," he said in a WhatsApp media group.

AFP correspondents near the scene in Shahr-e-naw, a commercial and residential neighbourhood, heard multiple blasts and gunfire, while Afghan media reported similar details.

Video circulating on social media showed people clamouring out of windows on the lower floors of the building, with the hotel sign -- in English and Chinese -- clearly visible.

Other video showed huge flames licking out of another section, with thick plumes of smoke.

A helicopter also made several passes of the area.

The hotel is popular with Chinese business visitors, who have flocked to Afghanistan since the Taliban's return in pursuit of high-risk but potentially lucrative business deals.

China, which shares a rugged 76-kilometre (47-mile) border with Afghanistan, has not officially recognised the Taliban government but is one of the few countries to maintain a full diplomatic presence there.

- Sensitive border -

Beijing has long feared Afghanistan could become a staging point for minority Uyghur separatists in China's sensitive border region of Xinjiang.

The Taliban have promised that Afghanistan would not be used as a base for militants and, in exchange, China has offered economic support and investment for Afghanistan's reconstruction.

Maintaining stability after decades of war in Afghanistan is Beijing's main consideration as it seeks to secure its borders and strategic infrastructure investments in neighbouring Pakistan, home to the China-Pakistan Economic Corridor.

The Taliban are at pains to portray Afghanistan as safe for diplomats and business people but two Russian embassy staff members were killed in a suicide bombing outside the mission in September in an attack claimed by IS.

The group also claimed responsibility for an attack on Pakistan's embassy in Kabul this month that Islamabad decried as an "assassination attempt" against the ambassador.

A security guard was wounded in that attack.

Despite owning the rights to major projects in Afghanistan, notably the Mes Aynak copper mine, China has not pushed any of these projects forward.

The Taliban are reliant on China to turn one of the world's largest copper deposits into a working mine that would help the cash-strapped and sanctions-hit nation recover.
