Feb 2 (Reuters) - China's state-owned ChemChina is nearing a deal to buy Swiss seeds and pesticides group Syngenta for around 43 billion Swiss francs ($42.2 billion), two people familiar with the matter said on Tuesday.
The deal, for roughly 470 Swiss francs per share, would be the biggest cross-border deal involving a Chinese buyer and mark an acceleration of a shakeup in the global agrochemicals industry. Negotiations are in final stages but nothing has been signed, the two sources said.
