Aug. 13 (Bloomberg) -- Carl Weinberg, chief economist and founder of High Frequency Economics, says the outlook for Japan is negative, as Japanese manufacturers feel extra pressure from surrounding countries in Asia. Weinberg also says that China's situation is "vexing and perplexing," but he is optimistic about growth. Weinberg speaks with Bloomberg's Carol Massar and Michael McKee on "Bloomberg On the Economy."
