Pension law changes are to be considered in a bid to save Tata's UK steel operations.
The government is said to be looking at ways of helping Tata to ease its pension liabilities in an effort to persuade the Indian company to abandon its planned sell-off.
First Minister Carwyn Jones, who has been with Mr Javid in Mumbai for talks with Tata, said that he was urging the Government to make legal changes.
The firm's £15 billion pension liabilities have always been seen as one of the biggest obstacles in finding a buyer for its UK assets, including the Port Talbot plant.
The First Minister of Wales, Carwyn Jones, has said a "very positive and constructive discussion" has been held in Mumbai over the future of Tata Steel's UK business.
The Indian conglomerate's board is drawing up a shortlist of potential buyers, although "nobody has yet emerged as a front runner or front runners", added Mr Jones, who has been joined in India by the Business Secretary Sajid Javid.
His comments come as hundreds of steelworkers marched through Westminster to call on the government to save the industry.
What Tata have said is that they need to go through each bid in detail and I welcome that, and that of course will take some time.
What's important here is not to rush things. We need certainty, of course, for the workers in the plants in Wales, where we get to a position where we see a sustainable long-term future for our steel industry.
Tata don't want to let workers down. It is uncertain... but we'll continue to talk to Tata, continue to listen to other bidders who have come forward with a view to getting the right outcome for people.

The issue still has to be resolved. We want a secure, guaranteed future for a foundation industry that is vital for our nation.
The whole of our manufacturing depends on British steel and I'm pleased that the government appear to be getting that message, but we want to make certain that those warm words are turned into positive action.
