Chinese manufacturers of everything from tricycles to truck winches, said on Wednesday at the opening of Asia’s biggest trade fair, that their orders were starting to recover from a steep plunge over the winter but that demand from Europe and particularly the United States remained anemic. The economy had grown at an annual pace of “around 6 percent” in the first quarter. That would be the slowest pace since quarterly records began in 1992, indicating that strong consumer spending and heavy government investments had failed to offset a nose dive in exports.
