BEIJING (REUTERS) - Chinese President Xi Jinping called for a return to "unity and harmony" on Thursday (Jan 31) as he welcomed gas-rich Qatar's emir to Beijing, amid a festering dispute that has seen some Arab states lead by Saudi Arabia severing relations with Doha.
Saudi Arabia, the United Arab Emirates, Bahrain and Egypt cut diplomatic, trade and transport ties with Qatar in June 2017.
They accuse Qatar of supporting terrorism and cultivating ties with Saudi Arabia's regional foe, Iran.
Qatar, which denies the charge, says the boycott seeks to curtail its sovereignty, while the row has defied mediation efforts by Kuwait and the United States which sees Gulf unity as essential to containing Iran.
The rift has shown no sign of being resolved soon. Qatar has been bolstering ties with its supporters, such as Turkey, with trade between those two expected to have risen by more than half in 2018.
China has largely stayed out of the dispute, calling for the problem to be resolved via talks, though has played host to senior Qatari officials since the spat began, including in December to Qatar's Foreign Minister.
Meeting in Beijing's Great Hall of the People, Mr Xi told Sheikh Tamim bin Hamad Al Thani that regional cooperation was an important basis for prosperity in the Gulf region, Chinese state television reported.
China supports the efforts of the Gulf Cooperation Council to seek an "appropriate resolution to disputes and contradictions via political and diplomatic means, to return unity and harmony between Gulf and Arab countries", Mr Xi said.
"China is willing to continue to play a constructive role according to the wishes of the Gulf Cooperation Council countries," Mr Xi added, according to the report, which did not make direct mention of the Gulf rift.
In remarks in front of reporters, Mr Xi called Sheikh Thani "an old friend and a good friend".
Sheikh Thani told Mr Xi that he was very happy with his personal friendship with him.
"We are ready to have bigger investments in China, in infrastructure or in any other field we see as important for us," he said.
"We are happy to provide China with liquid gas and we are ready to provide China with more in the near future. I am very happy to be in China."
Last October, state energy giant Qatar Petroleum said it had signed a five-year agreement to supply China with 600,000 tonnes of Liquefied Petroleum Gas (LPG) per year.
Earlier in January, state-owned Qatar Airways said it had acquired a 5 per cent stake in China Southern Airlines , in a move to gain access to the fast-growing Chinese market.
China has traditionally played little role in Middle East conflicts or diplomacy, despite its reliance on the region for oil, but it has been trying to raise its profile, especially in the Arab world. Saudi Arabia's King Salman visited Beijing in 2017.
However, China has had to walk a fine line, as it also has close ties with both Iran and Israel.
