China will develop its high-tech sector on a massive scale in the next decade, top officials vowed Friday, a day after meetings on the country's future policy priorities concluded in Beijing. The four days of closed-door discussions began on Monday and involved high-ranking officials outlining long-term strategies for the 15th Five-Year Plan, which starts next year. The country has poured support and investment into developing its science and technology sectors, part of ongoing efforts to present itself as a world leader in those areas ahead of Washington.
