month, the EU has made new regulations on the import of tea, some of the products of the highest pesticide residues allowed only the original standard 1/100-1/200 (in fact, produced by the original standard tea has no harm to human body), such as do not take effective measures, China\'s tea will be forced to withdraw from the EU market.. Now, developed countries often occur between the standard trade war, they are nominally in order to protect China\'s foreign trade within the three major structural changes reduced. So, in a very long period of time, developing countries in international trade pattern will be more and more disadvantageous position.
A positive effect:
Environmental barriers and green standards for an objective to promote the implementation of sustainable development. Economic development and environmental protection is the development of any country will face a contradiction. But the immediate economic interests tend to make people choose to destroy the environment for economic development of the road. Deforestation and hunting, exploit the practice of the present Earth\'s environment deteriorated sharply. Even in China, although already the environmental protection as a basic national policy, but according to incomplete statistics, the 1998 National impact on the environment exports amounted to $ 8.6 billion, accounting for 6.2% of total exports; serious pollution in 2000 products (such as dyes, leather products, printing and dyeing products, pulp, etc.) exports $ 11 billion, accounting for 5.1% of exports. The implementation of green standards will force China\'s enterprises in the production process to reduce environmental pollution, the use of green production system to produce green products. This objective will be to promote China\'s sustainable development strategy. Similarly, in a certain extent, will promote the development of world economy and world environmental protection tend to co-ordination and balance, help in the development of world economy, while protecting the ecological environment of the entire planet.
Quarantine standards and continuously improve packaging design standards, prompting countries to continuously improve their product quality and health and safety performance, safety of human life and health have a positive effect. In particular, the epidemic is now the world flora and fauna (such as foot and mouth disease, mad cow disease, wheat dwarf smut, bacterial wilt of corn, etc.) when the outbreak, coupled with genetically modified (GMO) security is still not scientifically determined, so in international trade, countries to develop relevant standards and strict implementation of quarantine is necessary.
