Teck Resources (TECK) and Anglo American must offer more to secure Ottawa's approval for their planned merger, The Wall Street Journal reported Tuesday, citing Canada's Industry Minister Melanie Joly.

In September, the companies agreed to combine in a merger of equals to form Anglo Teck.

While a decision on the takeover is expected next month, Anglo Teck's commitments to date are insufficient under Canada's foreign-investment laws, Joly was quoted as saying by the Journal.

A Teck spokesman said the companies continue to engage with the government, while a spokesman for Anglo declined to comment, according to the Journal.

Teck Resources, Anglo American, and representatives for Joly did not immediately respond to MT Newswires' request for comment on the matter.

Shares of Teck Resources were down 2.5% in recent Tuesday trading.
