China National Chemical Corp. is seeking to borrow a total of $35 billion to help fund the purchase of Syngenta AG, in a potential record financing for a Chinese acquisition. The Beijing-based company hired China Citic Bank International Ltd. to arrange a $15 billion loan facility, which will be fully guaranteed by ChemChina, people familiar with the matter said, asking not to be identified because the information is private. Bank meetings are scheduled this week for a separate $20 billion acquisition loan, to be borrowed by Syngenta and not guaranteed by ChemChina, according to an e-mailed statement dated Feb. 25. ChemChina agreed to buy Syngenta for $43 billion earlier this month in a deal that will transform it into the world's largest supplier of pesticides and agrochemicals. The planned loan dwarfs Chinese companies' previous overseas acquisition financing and may stoke concerns about the nation's businesses piling up debt in a push to buy foreign technology. The $15 billion facility being arranged by Citic Bank will likely be syndicated in Asia, according to the people. Terms are being finalized, they said. A spokeswoman for ChemChina declined to comment. The Wall Street Journal reported details of the Citic Bank facility earlier, citing unidentified people.
