More tigers are moving from Russia into northeastern China. This is because the environment is better for them to live in.

As human activities become less and the number of the wild animals is rising, tigers come to China for food.

Also, there is a cross-border corridor（跨境走廊）between China and Russia. It helps the tigers travel around freely. Data（数据）from a research team show that between 2013 and 2016, nearly 80 percent of the tigers moved across the corridor.

Besides, China started a number of projects to protect the tigers. As we all know, tigers need large areas to move around, so it’s important to build national parks. In 2021, the Northeast China Tiger and Leopard National Park was set up in Heilongjiang Province and Jilin Province. It covers around 14,100 square kilometers. The national park creates a shared home for the animals. As a result, the number of the tigers has grown.

One more reason is that experts from China and Russia work together to research on tiger protection. Many volunteers go to protect tigers around the forests every year. It’s believed that there will be more tigers in the near future.
