BEIJING, April 20 (Xinhua) -- Senior officials of China and India had an "extensive, deep and candid" discussion on boundary issues on Wednesday in Beijing, said a press release from the Chinese Foreign Ministry.

The U.S.-dominated International Space Station, which unsurprisingly blocks China, is scheduled to end its service in 2024. China's space station could be the only operational one in outer space, at least for a while.

"We are in a race against time ... We must intensify efforts to decarbonize our economies," Ban told the gathering at the signature ceremony.

In addition, China's traditional international competitiveness has been weakened, featuring decline in the growth rate of foreign trade and utilization of foreign capital, said the premier.

The Chinese government supports Chinese companies taking part in the infrastructure construction and industrialization in Morocco, he said, suggesting cooperation in the areas of industrial parks, high-speed railways and renewable energy.
