US President Barack Obama has warned China to handle the South China Sea dispute with cool and calm. Otherwise the US might take severe steps against it, which is expected to lead to World War 3.

“Where we see them violating international rules and norms, as we have seen in some cases in the South China Sea or in some of their behavior when it comes to economic policy, we’ve been very firm,” Obama said. “And we’ve indicated to them that there will be consequences.”

As the national leaders gather in Hangzhou for the G20 summit, some nations are trying to build their bond while a few are sharing tense vibes. The United States and China have not been in good terms for a long time but the flame of aggression ignited as the American president did not receive a warm welcome to the nation, which is hosting the summit for the very first time. There was no red carpet entrance organized for Obama, which showed that China was not willing to shake hands with America.

When Obama entered the Chinese airport, the officials from both nations were found exchanging heated comments. The unwelcoming attitude of the Eastern nation for Obama sparked several speculations and questions whether China did it intentionally. The Chinese foreign ministry spokeswoman came forward to justify whatever happened with the national leader of the US.

“I think if only the American group had respected the working arrangements first made with China, then this wouldn’t have occurred,” Hua Chunying said in Beijing as quoted by the ABC on Monday. “You saw that all the other country leaders used the stairs that China provided. Why was it that only the United States didn’t? These were the stairs the United States requested.”
