The differences between US are too big, too obvious. Some give and take is involved in this. Our trade gap is around 3% or thereabouts. We both have done remarkably well for trade. We will not sacrifice world prosperity to such differences,\u201d he said.

Both are answering five hours of questions from shareholders, journalists and analysts. \u201cI will be 88 in August. And 8 is a very good number in China. I hope this becomes the year when we get to acquire something in China, he added. Earlier, Buffett also said, \u201cBerkshire gains last quarter was enhanced by changes in US income-tax rules. Berkshire operating income was at record high in last quarter.
