Tangshan Iron and Steel Group, China's second-largest steel maker, plans to fully list, most likely on the southern Shenzhen stock exchange, a senior executive said on Wednesday.

Tangshan was formed from a merger last year between three local steel companies in northern China's Hebei province.

It has two listed units -- Tangshan Steel Co. Ltd. and Chengde Xinxin Vanadium and Titanium Co. .

"Our plan is to list in full, possibly in Shenzhen, but it's rather complicated," Chu Jiandong, vice general manager of Tangshan Iron and Steel Group, told Reuters on the sidelines of a conference in the northern Chinese coastal city of Qingdao.

He said the listing could happen in the next two years.

Tangshan had considered listing in South Korea, but that plan had proved difficult, Chu said. It may ultimately consider a share offer in Singapore, he added.

China is promoting consolidation of its fragmented steel industry to create a few modern giants, but some top down mergers of rusty state-owned mills may not result in the internationally competitive firms Beijing wants, industry officials have said.

Tangshan may consider more domestic acquisitions Chu said, but declined to specify targets.

Tangshan, which sources some of its iron ore domestically, was also interested in investing in overseas iron ore mines, Chu earlier told the conference.

By 2010, Tangshan planned a crude steel capacity of 30 million tonnes, he said, as well as 200,000 tonnes of vanadium residue and 35,000 tonnes of titanium dioxide.

The company produced 16.08 million tonnes of steel last year, second only to Shanghai's Baosteel Group.
