Thai Union Frozen Products PLC forecast a 20% hike in net profits and a 10-15% increase in sales revenue despite the strengthening baht. Net profit is expected to improve on 2001's Bt1.51bn (US$34.87m), while sales should rise 10-15% from Bt35.32bn in 2001.  TUF president Thiraphong Chansiri said that foreign exchange was undoubtedly the group's biggest challenge this year, while raw materials and the market were relatively stable.
