Mohamed Al-Mady also told Reuters on Sunday that SABIC shut down its plant in Japan after a devastating earthquake there but will resume operations on Monday.

He said Asian countries such as China and India were growth drivers despite the earthquake in Japan, while business in Europe was now slightly improving.

"Asia is the biggest growth market for SABIC this year. It is stabilizing in Europe, Europe is the weakest market but I think it is improving," Al-Mady said.

"We are very optimistic (that) 2011 will be a good year if not better, in general it will be another good year. Prices are ... improving in Asia, America, Europe," Al-Mady said.

Al-Mady added that around 70 percent of SABICS' products are exported, with the majority to Asia followed by the United States and other markets.

He said a 260,000 tons-per-year (tpy) polycarbonate plant at a giant complex in Jubail on the Gulf coast and owned by SABIC's affiliate Saudi Kayan Petrochemicals will start production in the coming months.

Plants at Kayan will come on stream this year and early next year, Al-Mady reiterated. There are 16 plants at the complex which will have an annual production capacity of around 6 million tons of petrochemicals including ethylene, propylene and ethylene glycol.
