China-US pork deal 'significant'
30 May 2013 Last updated at 10:05 BST
The biggest pork firm in China, Shuanghui International, has made a $4.7bn (£3.1bn) bid to take over the largest pork producer in the US, Smithfield Foods.
If the deal goes ahead it would be the largest takeover of a US company by a Chinese rival.
However, rival bidders may emerge as Smithfield has another 30 days to hold talks with other interested parties.
The BBC's Michelle Fleury said that the proposed takeover was "significant for several reasons".
