G20 ministers urge tighter tax rules for multinationals

CHENGDU, China: The world's major economies need to deepen cooperation on tax collection as companies seek to minimize the amount they pay to governments, finance ministers said Saturday.

The issue has become controversial in many countries, with multinational firms from Google to Starbucks facing accusations of not contributing appropriately to the economies where they make their money, and multi-billion-dollar merger proposals being partly driven by tax considerations.
