BRUSSELS (Reuters) - Dow Chemical <DOW.N> and DuPont <DD.N> have provided key data allowing European Union antitrust regulators to resume scrutiny of their $130 billion merger, the European Commission said on Wednesday.

The EU competition enforcer stopped its investigation last month after the companies failed to submit crucial information.

"We have received the missing information and the clock has been re-started. The new deadline for the Commission to take a decision is 28 February 2017," a Commission spokesman said in an email.

The Commission is worried the merger to create a giant in crop protection and seeds may reduce competition in these areas as well as certain petrochemicals.
