Reuters - Diplomats said Iran is on course to breach a threshold in its nuclear agreement within days but U.S. President Donald Trump, who has ratcheted up pressure on the Middle Eastern country, said there was �absolutely no time pressure� on the issue.

The prospect that Tehran could soon violate its nuclear commitments, a week after Trump called off air strikes on Iran at the last minute, has created additional diplomatic urgency to find a way out of the crisis.

Iran had set Thursday as a deadline beyond which it would exceed the threshold for stockpiles of enriched uranium allowed under its 2015 nuclear deal with major powers, which Tehran is still following even though Washington abandoned it last year.

The diplomats, citing U.N. inspectors� data, said the Islamic Republic was on course to exceed the limits soon by accumulating more enriched uranium than permitted but it had not done so by Thursday.

However, Trump said of Iran on Friday: �We have a lot of time. There�s no rush.�

�They can take their time. There�s absolutely no time pressure. I think in the end, hopefully, it�s going to work out. If it does, great - and if it doesn�t, you�ll be hearing about it,� he said as he greeted Indian Prime Minister Narendra Modi on the sidelines of a G20 summit in Osaka.

Other world leaders gathered in Japan continued to express concern about Iran, even as Trump appeared relaxed.

Chinese President Xi Jinping said the Gulf region was �standing at a crossroads of war and peace�, calling for calm and restraint and talks to resolve the issue.

�China always stands on the side of peace and opposes war,� state news agency Xinhua paraphrased Xi as saying in Osaka. �All parties must remain calm and exercise restraint, strengthen dialogue and consultations, and jointly safeguard regional peace and stability.�

European Council President Donald Tusk, also at the G20, expressed concern about Iran potentially breaching the pact, saying the European Union would continue to monitor Tehran�s compliance.

�We strongly urge Iran to continue the full implementation of all its commitments under the nuclear deal, and we take very seriously the possibility of any breach of its commitment,� he told a news conference.

�Maintaining the nuclear deal is in the regional and international security interest,� Tusk said. �The EU is committed to the deal as long as Iran continues to uphold it.�

One diplomat in Vienna, headquarters of the U.N. nuclear agency the International Atomic Energy Agency (IAEA), said on Thursday: �They haven�t reached the limit ... It�s more likely to be at the weekend if they do it.�
