二 |     (ECNS) -- China has expanded its 240-hour visa-free transit policy to citizens of Kyrgyzstan and Vietnam, bringing the number of countries covered by the policy to 57, according to the National Immigration Administration (NIA) on Wednesday.    Under the new arrangement, which took effect on Aug. 20, citizens of Kyrgyzstan and Vietnam holding ordinary passports and interline passenger tickets with confirmed dates and itineraries bound for a third country or region may enter China through any of the 65 ports across the country and stay up to 240 hours, or 10 days, without a visa, according to the National Immigration Administration (NIA).    Citizens of these two countries who hold ordinary passports will also be eligible for the 30-day visa-free entry policy for Hainan Province in south China starting the same day. This will allow them to enter the province through Hainan's open ports and stay visa-free for up to 30 days. With these additions, the number of countries covered by this Hainan visa-free policy has now reached 61.    During the visa-free period, travelers are permitted to engage in tourism, business, exchange visits and family visits. However, the two policies do not cover employment, study or journalistic activities, which still require appropriate visas, the NIA said.    An NIA official said the measures are part of efforts to advance high-level opening-up and facilitate exchanges and cooperation with neighboring countries. Looking forward, the NIA will continue to support international travel while ensuring orderly border management.    (By Intern Liu Shuagjing, Zhang Dongfang)                    。来源：同花顺iFinD盘面上，行业板块中，农业服务、贵金属、养殖业、农产品加工、酒店餐饮等板块涨幅居前，医疗服务、电力、房地产开发、房地产服务、煤炭开采加工等板块领跌。概念板块中，大豆、宠物经济、动物疫苗、猪肉、养鸡等板块领涨，CRO概念、TOPCON电池、抽水蓄能、绿电等板块跌幅居前。CRO概念中，药明康德、凯莱英跌停，康龙化成跌超12%，药石科技跌10.55%，博腾股份、九州药业跌超9%。消息上，据环球网消息，美国总统拜登当地时间12日签署了一项鼓励美国生物技术生产和研究的行政命令。“美国之音”等媒体报道拜登签署行政命令时解读说，此举是在“回应中国在生物技术方面的挑战”。北向资金方面，北向资金上午净流入超32亿元，其中沪股通流入超9亿元，深股通流入超23亿元。个股方面，目前涨停股部分如下：西藏矿业(9.99%)、中洲控股(9.96%)、方大集团(9.95%)、中百集团(9.94%)、弘业期货(9.99%)。其他跌停股部分如下：萃华珠宝(-9.97%)、粤宏远A(-10.06%)、贵绳股份(-9.99%)、博深股份(-9.97%)。换手率前五个股为：钜泉科技、贝肯能源、弘业期货、胜通能源、联特科技，分别为48.828%、44.411%、43.272%、40.149%、33.290%。山西证券认为，受流动性和企业盈利边际持续下行的影响，A股目前大概率难以启动新一轮趋势性行情。但综合来看，随着调整时间的延续以及幅度的加大，A股整体估值已经进入低估区间，以1年期维度看，市场已经有收获趋势性行情的基础，建议逐步关注和布局弹性大、盈利能力强和具有较优成长性及估值修复空间的行业。返回搜狐，查看更多责任编辑：
