U.S. companies are really excited about finding new medicines in China! Big medicine companies, called "Big Pharma," like Merck, are looking to China more than ever. Last year, about 30% of the big medicine deals started in China. That's a big jump from just 20% the year before! Not long ago, only a few companies wanted to work with China. However, many Chinese companies are now making really amazing drugs. These companies can also test their medicines quickly and cheaper than in America. This makes investors really happy! One special company, Summit Therapeutics, found a cancer drug in China that was better than a famous medicine from Merck. This made everyone pay attention! Now, more U.S. companies are going to China to find new drugs. But people have mixed feelings about this. Some think it’s great because it helps bring new medicines to everyone for a lower price. Others worry it could hurt American companies since they might not get chosen for new deals. Another important point is that Chinese drug companies used to not be very popular, but that has changed. Now, they are making better and better drugs, and they need help from U.S. companies. Some U.S. companies like Gilead are also looking for medicines in China, just like they do in America. However, some U.S. leaders are worried. They might want to stop these deals to protect American jobs. This has already happened in technology. The future of drug-making is changing very quickly, and we don’t know yet how it's going to end. Overall, it’s a race to find new medicines, and both China and the U.S. are competing hard! It's a big journey to make medicine better and cheaper for everyone.
