On Thursday, Wang Yaping delivered a lecture to students from Shenzhou X, becoming China's first teacher in space. Her feat was hailed as a breakthrough for China's manned mission in space. The Jiaolong manned deep-sea submersible is an equally, if not more, important stride for China's deep-sea technology mission.

On Tuesday, Jiaolong carried its first scientist on its second deep-sea dive. It had completed its maiden dive of its first application-oriented trial mission on Monday. The successful deep-sea dive of Jiaolong means China has completed the first tier of manned deep-sea diving, and its research and resource exploration abilities have greatly advanced.

Some people believe that the success of the Jiaolong manned deep-sea submersible's mission, which will provide technological support to China's ocean resource development, is more important than the Shenzhou X mission.

Of course, there are a few people who believe China's deep-sea diving technology lags far behind that of Europe and the United States, and some who are worried that China is developing deep-sea diving technology to seize the oceans' resources and even strengthen its deep-sea military power. Such people either ignore China's fundamental reality, culture and national strategy, or are prejudiced against Beijing's peaceful development.

As a great power with relatively low per capita resources, China has no option but to develop its deep-sea technology to meet the strategic demand of its rapid development. China's top priority is to develop its economy, which puts a huge demand on resources and energy. Therefore, the Jiaolong's deep-sea diving mission cannot be aimed at developing deep-sea military technology. Its goal is to simply explore and exploit deep-sea resources.

Apart from striving to develop its economy and improve its people's livelihood and living standards, China is the "world factory" and has become the engine of global economic recovery. All these demand huge amounts of resources, for which it has to explore and exploit the oceans.

People who are familiar with this reality and the difficulties facing China will not have any problem understanding why it has expedited its deep-sea resource exploration program. Although Beijing can exploit the potential of the East China Sea and the South China Sea, which have abundant resources, it exercises restraint to show its commitment to peaceful development.

President Xi Jinping said at his recent meeting with US President Barack Obama that China will not trigger conflicts or fight with neighboring countries.

China wants to be other countries' partner, not opponent; it wants to develop cooperation and win-win relationships with mutual respect with other countries. And it is committed to being a responsible great power despite some countries' suspicion, provocations and attempts to contain its rise.

Some countries and people antagonistic to Beijing will resort to the use of the "China threat" theory again to smear its image after the success of the Shenzhou X and Jiaolong missions.

The fact is that despite facing great challenges, from energy and military to technology and security, China has never threatened any other country.

Moreover, despite China's restraint and tolerance, some neighboring countries that have territorial disputes with China are trying to create trouble, which shows that China, not other countries, is the threatened party.

If China had any intention of ignoring other countries' interests, it would have started exploring and exploiting the coastal waters to meet its resource demand instead of developing its deep-sea diving technology. But still some people and countries use the "China technology threat" and "China energy threat" theories, because they cannot accept China's peaceful rise.

Why don't these people and countries understand that it is much more urgent and important for China to develop deep-sea technology to meet its resource demand than to strengthen its military power?

It's time China took steps to clarify the truth and dispel the international community's fears by putting the media and its diplomats into action.
